AB  - Cavitation erosion application could be observed as dangerous phenomena which have large influence on engineering materials behavior and life time in working conditions. This phenomenon is related to fluid flow conditions, which could cause pits and defects formation resulting in mechanical properties degradation, as well as potential risk of failure of the part. In this paper results for cordierite and alumina (low cement high alumina castable, LCC), based refractories subjected to cavitation erosion testing will be presented. Testing of the samples will be according standard method, with stationary sample in ultrasonic vibratory method. Degradation of the samples will be monitored by mass and volume loss, as well as changes in morphological characteristics. Image analysis will be applied for pits characteristics (number, average diameter, area, roundness) determination.

AB  - Engineering materials are often used in various operating conditions including high temperatures, 
pressure, aggressive solutions, or cavitation erosion. The phenomenon of cavitation erosion is expected 
when fluid flow is present, which contains equipment such as turbine blades, high-speed propellers, or 
pump parts. Cavitation erosion usually causes surface degradation of material with defects that appear in 
the form of pits and fractures. Such loss of material leads not only to surface degradation but usually also 
to strength deterioration with the potential risk of failure and therefore also to shortening of material 
lifetime, thus requiring additional costs for failure analysis, repair, and replacement of parts. This paper 
will present the results regarding the resistance of various engineering materials to cavitation erosion. As 
materials, austenitic stainless steel 316L and CuAlNi shape memory alloy are selected and studied. The 
comparison of the behavior between these two materials in cavitation erosion conditions will be shown 
based on the results of mass loss and morphology analysis of the pits formed at the surface over time. Image 
analysis tools will be applied in order to quantify the surface damage level and to analyze selected 
morphology descriptors.

AB  - Cavitation erosion behavior of engineering materials is very important for various applications, such are
industrial/military/power station equipment and parts, such as pump impellers, delicately balanced high-speed propellers
and turbine blades. Cavitation erosion could cause pits and fractures, which usually lead to potential risk of failure, as
well as potential injury for workers and others; loss of revenue, due to equipment downtime and the extra costs of failure
analysis, repair and replacement of parts.
In this paper cavitation erosion of different engineering materials will be investigated. Selected materials are: metals
(austenitic stainless steel 316L and CuAlNi shape memory sample), ceramics (cordierite) and polymer composite (epoxycarbon
composite). Cavitation erosion behavior of selected samples will be compared using mass loss results and image
analysis results applied on pits (damage) analysis in order to calculate damage level.

AB  - Implementation of statistical analysis for monitoring the formation and propagation of defects that occurred due to
exposure of the material to thermal shock and cavitation is presented in this study. Results of two groups of materials are
shown: refractory concrete sintered at three temperatures and ceramic materials based on cordierite and zircon. Aluminabased
refractory concretes were subjected to thermal stability test, while the surface morphological changes regarding the
defects were monitored after a certain number of thermal shock cycles. Cordierite and zircon based materials were initially
subjected to cavitation testing while after specified time periods, morphological changes in the surface defects were
analyzed. Besides the standardized methods, non-destructive testing of materials was applied for monitoring the surface
changes. Cameras, microscopes, and numerous software enable recording images of sample surface with appropriate
magnifications as well as monitoring and quantifying the surface damage degree with various image analysis tools. Thus,
this approach offers the quantification of selected morphological descriptors regarding the defects. Obtained values were
then subjected to pattern recognition method, the principal component analysis that can provide information on extracted
morphological descriptors by describing the main difference among observed defects and identifying variations among
them. As a result, a better insight into surface degradation that occurs during exposure to extreme conditions was obtained.
The multivariate analysis provided grouping and thus reduction of the descriptors while maintaining the highest
percentage of variance unchangeable. More precisely, the analysis extracted the most informative descriptors that should
be observed for monitoring changes in surface defects and determining a degradation mechanism.

AB  - Explosion welding is often used when conventional welding methods cannot provide welded
joint of two dissimilar materials, but also when some specific geometry should be welded, or large
surfaces of metal plates. The formation of a joint in explosive welding is based on the dynamic effect
of the high pressure created by the explosion. For this purpose, most often some industrial explosives
of low detonation parameters are used, and one of them is DEMEX, produced by TRAYAL,
Serbia. In this research DEMEX was applied to weld plates of two different types of steel. Prior to
the experimental procedure of welding, the selected metal plates, the explosive obtained from the
producer was subjected to initial quality control: measurement of its bulk density and detonation
velocity, using optical probes and a photodetector connected with an electronic counter. The experimental
setup for welding was as follows: explosive DEMEX in powdery state was applied in a uniform
layer over the upper plate, which was horizontally placed over the lower plate, in parallel
position, with small wooden spacers, marginally placed between them. Activation was performed by
an electro-detonating cap and a small booster of plastic explosive. The welded joint was examined
using methods of ultrasonic defectoscopy, liquid penetrants testing and microstructural analysis of
the welded joint. Cross-sectional microstructural analyses of the welded plates were performed
using a stereo and optical microscope to analyze the weld zone.

AB  - Explosively welded metal plates of large surfaces or specific geometries are used in equipment for 
the production of electricity from renewable sources. In explosive welding, the energy of a 
controlled detonation is used to create a joint, when one metal part collides with another at high 
speed forming a weavy bonded interface. Explosive welding is used in the production of specialized 
components for renewable energy sources, such as parts of wind farms or turbines, because enables 
strong and secure connections between different types of metal or material. This technique can also 
be applied in the production of specific components for solar industry, such as solar panel supports 
that require strong and reliable connections, often between dissimilar materials that are difficult to 
weld with conventional methods. In addition, explosive welding can be useful in the production of 
batteries for renewable energy storage, where it is crucial to ensure that the connections are 
mechanical and electrically reliable. For such structures it is important to be able to perform in situ 
monitoring using nondestructive techniques to check the success of the performed welding on the 
whole pieces or products made this way. This work considers the application of non-destructive and 
destructive techniques to examine the quality of explosively welded joints of two different sets of 
metal plates: aluminum alloy-steel and carbon steel- highly wear resistant alloy steel, with two 
explosives, Amonex and Demex. Inspection of the joints was carried out using surface methods and 
non-destructive volumetric methods. The following techniques were applied: visual method, liquid 
penetrant testing, X-ray and ultrasound defectoscopy. To confirm the results of non-destructive 
techniques, a microstructural analysis of the cross-section of the welded joint was performed. The 
application of non-destructive testing techniques in testing the quality of explosively welded joints 
contributes to the reduction of costs that would be caused by destructive tests, since these 
techniques can be used to monitor the success of the process itself and thus improve the 
technological process of producing bimetallic joints by explosive welding.

ili turbina, jer omogućava čvrste i sigurne spojeve između različitih vrsta metala. Ova tehnika se 
može primeniti i u izradi specifičnih komponenti za solarnu industriju, kao što su nosači solarnih 
panela koji zahtevaju snažne i pouzdane veze, neretko između raznorodnih materijala koje je teško 
zavariti konvencionalnim postupcima. Osim toga, eksplozivno zavarivanje može biti korisno u 
proizvodnji baterija za skladištenje obnovljive energije, gde je ključno osigurati da su spojevi 
mehanički i električki pouzdani. Za primenu u takvim konstrukcijama važno je da se može vršiti in 
situ kontrola primenom nedestruktivnih tehnika kako bi se proverila uspešnost izvršenog 
zavarivanja celih komada ili proizvoda dobijenih na ovaj način. U ovom radu prikazana je primena 
nedestruktivnih i destruktivnih tehnika za ispitivanje kvaliteta eksplozivno zavarenih spojeva dva 
različita seta metalnih ploča: aluminijumska legura-čelik i ugljenični čelik-alatni čelik, sa dva 
eksploziva, Amonex i Demex. Ispitivanje kvaliteta ostvarenih spojeva vršeno je površinskim 
metodama i zapreminskim metodama bez razaranja i sa razaranjem. Primenjene su sledeće tehnike 
bez razaranja: vizuelna metoda, ispitivanje tečnim penetrantima, radiografija i ultrazvučno 
ispitivanje. Kako bi se rezultati nedestruktivnih tehnika potvrdili, izvšena je i mikrostrukturna 
analiza poprečnog preseka zavarenog spoja. Primena tehnika ispitivanja bez razaranja u 
ispitivanju kvaliteta eksplozivno zavarenih spojeva doprinosi smanjenju troškova kada se vrše 
destruktivna ispitivanja. Ovim tehnikama može pratiti uspešnost samog procesa i na taj način 
poboljšati tehnološki proces izrade bimetalnih spojeva eksplozivnim zavarivanjem.

AB  - Cavitation erosion causes serious failures, as well as potential injury for workers and others; loss of revenue, due to equipment downtime and the extra costs of failure analysis, repair, and replacement. Erosion behavior of engineering materials caused by cavitation can be observed in various equipments, such are pump impellers, high-speed propellers, and turbine blades, or equipment in conditions that include fluid flow.
In this paper cavitation erosion of refractory ceramic materials commonly used as coatings for foundry application, will be investigated. Selected materials are ceramics based on a talk with the addition of zeolite from two domestic localities (Igros and Zlatokop), and cordierite ceramics.
Samples were formed, pressed, and sintered at 1200 °C. Prepared samples were subjected to the cavitation erosion test by using the ultrasonic vibration method with a stationary sample.
The cavitation erosion behavior of selected samples will be analyzed using mass loss results and image analysis applied to formed pits.

AB  - Thermobaric explosive mixtures are recently widely studied due to their specific energetic effects, 
especially regarding thermal output during the post-detonation combustion phase. Most of these 
mixtures contain as a very important component some metal powder fuel, which burns in contact 
with atmosphere oxygen or the oxidant component of the mixture after the initiation. This 
combustion process releases a large amount of thermal energy, which is recognized as a potential 
source of other types of energy if it were released and further transformed under controlled 
conditions. In this research, the possibility of controlled combustion of waste thermobaric 
explosives as a source of energy was considered. Thermobaric compositions containing aluminium, 
magnesium and boron powder were analysed. EXPLO5 software was used to calculate parameters 
of their isochoric and adiabatic combustion, to predict the potential thermal output of these 
mixtures. The selected compositions were experimentally examined in small samples by the method 
of calorimetry to determine their energetic potential during combustion in atmosphere of inert gas 
in a calorimetric bomb. The obtained results encourage further research into the possible 
applications of this thermal energy, which can be released not only in the reaction of a destructive 
explosion, but also by combustion under controlled conditions, as a quaternary recycling of waste 
explosives - a potential source of heat and electric energy.

количина енергије у врло кратком времену, која се примењује за различите
врсте корисног рада, како у привредне, тако и у војне сврхе. Поред приме-
не експлозивних материја у убојним средствима и за рушење у рударству и
грађевинарству, енергија детонације нашла је примену и у заваривању и об-
ради метала. Применом енергије настале детонационим разлагањем експло-
зива могуће је извршити заваривање метала, обликовање, резање, утицати на
повећање његове чврстоће итд. Технологија заваривања експлозивом почела
се развијати половином 20. века, и данас је заступљена за израду делова ва-
здухоплова, наоружања и војне опреме, оклопних плоча са повећаном бали-
стичком заштитом, специјалних цистерни, топлотних измењивача, посуда под
притиском,специјалних индустријских резних алата и свих других производа
који се не могу израдити неким другим конвенционалним поступком обраде
металних материјала. Такође, значајна предност ове технологије је могућност
израде вишеслојних материјала великих површина.
Заваривање метала експлозијом остварује се као последица веома брзог
судара метала под дејством продуката детонације, уз појаву високог притиска
и пластичних деформација у облику таласа на граници споја и адијабатског
локалног загревања површинских слојева металних материјала.
У оквиру овог рада анализирана је могућност примене привредног екс-
плозива Amonex у заваривању плоча од опружног челика 51CrV4 и конструк-
ционог челика S355 J2. За изабрани експлозив Amonex, који је произведен у
Корпорацији ТРАЈАЛ, претходно су измерене насипна густина и брзина дето-
нације, где је коришћена метода мерења времена између две тачке у експлозив-
ном пуњењу коришћењем електронског бројача са оптичким давачима.
Током свих реализованих експеримената коришћена је иста поставка
плоча. Коришћене су плоче димензија 150×200 mm. Горња плоча од опружног
челика ознаке 51CrV4 дебљине 3 mm, која је убрзавана енергијом експлозије,
била је постављена паралелно са непомичном доњом плочом израђеном од кон-
струкционог челика ознаке S355 J2 дебљине 10 mm. Почетно одстојање између
плоча износило је 4 mm, где су коришћена по 4 ивично постављена одстој-
ника израђена од пластичне масе поли(метил метакрилат), скраћено PMMA.
Коришћена су експлозивна пуњења три различите масе експлозива Amonex,
који је у одговарајућем слоју био равномерно слободно насут на горњу плочу.
Таквим експериментима омогућено је одређивање зависности квалитета зава-
реног споја од масе примењеног експлозива.
За одређивање квалитета завареног споја примењене су две технике ис-
питивања без разарања: метода са течним пенетрантима MR68C и испитивање
ултразвучним дефектоскопом ознаке Phasor XS. Потом су плоче исечене за
даљу анализу, где су извршени микроскопски преглед пресека заварених споје-
ва помоћу оптичког микроскопа типа Leitz Metalloplan, опремљеног камером
DFC 295 и софтвером за обраду слике LAS 4.3.1. Ударна жилавост споја из-
међу експлозијом заварених плоча испитана је на одговарајуће припремљеним
епруветама помоћу Шарпијевог клатна ознаке Schenck trebel.
Резултати испитивања показали су да експлозив Amonex може наћи
примену у експлозивном заваривању, a најбољи резултати постигнути су код
узорка завареног средњом количином експлозива. Код овог узорка добијене су
највише вредности ударне жилавости на Шарпијевом клатну, док је код трећег
завареног споја дошло до наглог пада ударне жилавости услед формирања
међуслоја, растопљене фазе на споју, што је потврђено микроскопском ана-
лизом. Ултразвучна дефектоскопија је показала да средњи узорак има највећу
површину завареног споја, а узорак са најмање експлозива најмању површину
завареног споја.
AB  - Detonation of explosive substances releases a large amount of energy
in a very short time, which is used for various types of useful work, both for
economic and military purposes. In addition to the use of explosive substances in
ordnance and for demolition in mining and construction, detonation energy has
found its application in welding and metal processing. By applying the energy generated
by the detonation of explosives, it is possible to weld metal, shape it, cut it, increase
its solidity, etc. Explosion welding technology began to develop in the middle
of the 20th century, and today it is used for the production of aircraft parts, weaponsand military equipment, armour plates with increased ballistic protection, special
tanks, heat exchangers, pressure vessels, special industrial cutting tools and all other
products which cannot be produced by any other conventional method of processing
metal materials. Also, a significant advantage of this technology is the possibility of
manufacturing multi-layer materials of large surfaces.
The explosion welding of metals is done as a result of the very fast collision of
metals under the effect of detonation products, with the appearance of high pressure
and plastic deformations in the form of waves at the fusion line and adiabatic local
heating of the surface layers of metal materials.
In this paper, the possibility of using commercial explosive Amonex for the
welding of plates made of 51CrV4 spring steel and S355 J2 structural steel was analysed.
For the selected explosive Amonex, which was produced by TRAJAL Corporation,
the bulk density and detonation velocity were previously measured, whereby the
method of measuring the time between two points in the explosive charge using an
electronic counter with optical sensors was used.
During all conducted experiments, the same arrangement of plates was used.
Plates of dimension 150×200 mm were used. The upper plate of 3 mm thick 51CrV4
spring steel, which was accelerated by the energy of the explosion, was placed parallel
to a stationary lower plate made of 10 mm thick S355 J2 structural steel. The
initial distance between the plates was 4 mm, where 4 edge spacers made of plastic
mass poly(methyl methacrylate), abbreviated PMMA, were used. Explosive charges
of three different masses of Amonex explosive were used, which was evenly and freely
poured in the appropriate layer on the upper plate. Such experiments made it possible
to determine the dependence of the quality of the welded joint on the mass of
the explosive used.
To determine the quality of the welded joint, two non-destructive testing techniques
were applied: the method with liquid penetrants MR68C and testing with
an ultrasonic defectoscope Phasor XS. Then the plates were cut for further analysis,
whereby the microscopic examination of the sections of the welded joints was performed
using the Leitz Metalloplan optical microscope equipped with a DFC 295
camera and LAS 4.3.1 image processing software. The impact toughness of the joint
between the explosion-welded plates was tested on appropriately prepared test tubes
using the Charpy pendulum Schenck trebel.
The test results showed that Amonex explosive can be used in explosion welding,
and the best results were achieved with a sample welded with a medium amount
of explosive. In this sample, the highest values of impact toughness were obtained on
the Charpy pendulum, while in the third welded joint there was a sudden decrease in
impact toughness due to the formation of an intermediate layer, a molten phase at the
joint, which was confirmed by microscopic analysis. Ultrasonic defectoscopy showed
that the middle sample had the largest area of the welded joint, and the sample with
the least explosive had the smallest area of the welded joint.

AB  - In this study we investigated the effect of cold rolling reductions and different annealing conditions, on the mechanical
properties and corrosion resistance of an AA5182 type Al-Mg alloy. Material was industrially produced and supplied as
hot rolled 12 mm thick plates. Further lab-processing included cold rolling with 40-85% reduction in thickness, and 2h
of annealing in the range of temperatures from 300-350°C. Annealed specimens were used for room temperature tensile
testing while corrosion testing was performed on the annealed and sensitized specimens. Intergranular corrosion (IGC)
susceptibility was determined by nitric acid mass loss test (NAMLT) for the selected states.
The results showed that corrosion resistance, tensile strength and yield point elongation were mostly affected by a degree
of cold deformation. It was found that increasing in cold rolling reduction from 40-85% before annealing causes an
improved strength level due to grain size refinement. However, yield point elongation became more pronounced and a
tendency towards Lüdering as undesirable surface appearance was increased. NAMLT testing showed that the material
was corrosion resistant in as-annealed condition while it became susceptible to intergranular corrosion after sensitization
treatment. IGC susceptibility of sensitized specimens increases with cold rolling reduction and a grain size refinement.

AB  - Besides their application in munitions and armaments, explosives have a significant role in industrial applications, such as cladding or welding of metal plates. In the process of explosion welding, the energy of explosive detonation is used to achieve a metallurgical bond between two metal components, which are metallurgically compatible, but also those that are non-weldable by conventional methods. For this purpose, most often explosives of low values of detonation velocity are used, in order to avoid severe damage to the processed metal plates.
The aim of this study was to investigate the possibility to use the industrial explosive Amonex, which belongs to a group of low-to-middle detonation velocity explosives, for welding of metallic materials. It consists of ammonium nitrate and TNT as energetic components and other inert ingredients and has a powdery consistency, easily applicable in a desirable layer over the metal plates to be welded. Within this research, Amonex was applied to weld plates of aluminium Al 2024 and steel Č0345. Besides the initial data on the used metal plates, the main properties of the used explosives are also given, since based on these properties the needed quantity of explosive was estimated. The procedure of welding was carried out in the configuration of parallel plates, and afterward the welded joint was examined. Ultrasonic method and chemical penetrants were used as non-destructive techniques, and then the samples were cut from the welded plate using water-jet, in order to perform microscopic analyses on the cross-section and to determine the indentation hardness in the area of the joint. It was observed that a good-quality welded joint was obtained, and that the selected explosive may find further application in this area.

AB  - The pattern recognition approach, explored by this study, applies the principal component
analysis (PCA) as the most widely used statistical method with the aim of assessing the initiation
and propagation of the cracks and defects that appear on the surface of material exposed to the
cavitation. The experiment was performed in four stages: (a) synthesis of two ceramic materials
(cordierite and zircon); (b) subjecting the samples to the cavitation; (c) using image analysis
software for collecting the data about morphological characteristics that describe defects; (d)
principal component analysis as a pattern recognition tool in order to characterize the defects at
the material surface. Besides that, according to standard, cavitation erosion was monitored by
determining material mass loss during the cavitation. Large experimental datasets collected from
morphological descriptors by image analysis are multivariate and difficult to interpret, thus are
processed by principal component analysis as the most informative technique for extracting
possible differences. The performed approach proved that this method has a great potential for
better assessment of induced defects by proper distinguishing among them at different levels and
that can be considered a very efficient and cost-effective one.

AB  - In many industrial processes that include fluid flow, cavitation erosion of different engineering
structures (pumps, turbines, water levels, valves, etc.) during their operation is expected. Metallic,
ceramic, and composite materials are usual candidates considered for application in such extreme
conditions. In this study, the idea is to synthesize refractory ceramic material based on talc with
the addition of zeolite for utilization as protective coatings in cavitating conditions. Two talc-based
refractories with zeolites from two Serbian deposits were produced. The behaviors of the samples
in simulated cavitation conditions were examined by an advanced non-destructive methodology
consisting of monitoring mass loss and surface degradation using image analysis compiled with
principal component analysis (PCA), interior degradation by ultrasonic measurements, and the
microstructure by a scanning electron microscope (SEM). Lower mass loss, surface degradation level,
and modeled strength decrease indicated better cavitation resistance of the sample with Igros zeolite,
whereby measured strength values validated the model. For the chosen critical strength, the critical
cavitation period as well as critical morphological descriptors, Area and Diameter (max and min),
were determined. A Young’s elasticity modulus decrease indicated that surface damage influence
progressed towards interior of the material. It can be concluded that the proposed methodology
approach is efficient and reliable in predicting the materials’ service life in extreme conditions.

AB  - The aim of this study was to investigate the possibility to
use the industrial explosive Amonex, which belongs to a
group of low-to-middle detonation velocity explosives, for
welding of metallic materials. It consists of ammonium
nitrate and TNT as energetic components and other inert
ingredients and has a powdery consistency, easily applicable in a desirable layer over the metal plates to be welded.
Within this research, Amonex was applied to weld plates of
aluminium Al 2024 and steel 1.0216 (according to EN
10027-2). The procedure of welding was carried out in the
configuration of parallel plates, and afterwards the welded
joint was examined. Ultrasonic method and infrared imaging were used as non-destructive techniques, and then the
samples were cut from the welded plate using water-jet, in
order to perform microscopic analyses of the cross-section
in the joint area. It was observed that a good-quality welded
joint was obtained, and that the selected explosive may find
further application in this area. However, certain nonwelded area was observed, encouraging future modification
of the welding procedure set-up.

TNT-a kao energetskih komponenti i drugih inertnih sastojaka, ima praškastu strukturu i lako se nanosi u željenom

takođe su uočene i određene površine nezavarenog područja,

turbine engines for aircrafts, power and nuclear power plants, different types of furnaces,
including blast furnaces, some fuel cells, industrial gas turbines, different types of reactors,
engines, electronic and lighting devices, and many others. Demands for high-temperature
materials are becoming more and more challenging every year. To perform efficiently,
effectively and at the same time to be economically viable, the materials used at high
temperatures must have certain characteristics that are particularly expected for applying
under such extreme conditions, for example, the strength and thermal resistance. In the
present review, some important requirements that should be satisfied by high temperature
materials will be discussed. Furthermore, the focus is put on refractory concretes, ceramics,
intermetallic alloys, and composites as four different categories of these materials, which are
also considered in respect to possibilities to overcome some of the current challenges.
AB  - U visokotemperaturske materijale spada široki spektar materijala koji se koriste u industriji, za primenu poput turbina za motore i avione, termo i nuklearne elektrane, različite tipove peći uključujući visoku peć, gorivne ćelije, turbine za različiite namene u industriji, razne vrste reaktora, motora, uređaja u elektronici i osvetljenju, kao i mnoge druge. Svake godine zahtevi za visokotemperaturske materijale postaju sve izazovniji. Da bi se ostvarila efikasnost i efektivnost, i da bi se istovremeno postigla ekonomska održivost, materijali koji se koriste na visokim temperaturama moraju zadovoljiti određene zahteve i imati svojstva koja se očekuju u tako ekspremnim uslovima, kao što su, na primer čvrstoća i otpornost na povišene temperature. U ovom preglednom radu razmatrani su neki od značajnih zahteva koji moraju biti zadovoljeni
za visokotemperaturske materijale. Rad se odnosi na vatrostalne betone, keramiku, intermetalne legure i kompozite, kao četiri različite kategorije ove vrste materijala. Navedeni materijali su razmatrani u pogledu mogućnosti prevazilaženja nekih trenutnih izazova.

Da bi se ostvarila efikasnost i efektivnost, i da bi se istovremeno postigla ekonomska održivost, materijali koji se koriste na visokim temperaturama moraju zadovoljiti određene zahteve i imati svojstva koja se očekuju u tako ekspremnim uslovima, kao što su, na primer čvrstoća i otpornost na povišene temperature. U ovom preglednom radu razmatrani su neki od značajnih zahteva koji moraju biti zadovoljeni
za visokotemperaturske materijale. Rad se odnosi na vatrostalne betone, keramiku, intermetalne legure i kompozite, kao četiri različite kategorije ove vrste materijala. Navedeni materijali su razmatrani u pogledu mogućnosti prevazilaženja nekih trenutnih izazova.",

AB  - The effect of one-step and a new (short) two-step aging process on the resistance to stress corrosion cracking of an aluminum alloy 7000 series was investigated, using slow strain rate test and fracture mechanics method. The aging level in the tested alloy was evaluated by means of scanning electron microscopy and measurements of electrical resistivity. It was shown that the alloy after the new two-step aging is significantly more resistant to stress corrosion cracking. Values of tensile properties and fracture toughness are similar for both thermal states. Processes that take place at the crack tip have been considered. The effect of the testing solution temperature on the crack growth rate on the plateau was determined. Two values of the apparent activation energy were obtained. These values correspond to different processes that control crack growth rate on the plateau at higher and lower temperatures.

Stepen starenja ispitivane legure je procenjen primenom skening elektronske mikroskopije i na osnovu merenja električne otpornosti. Pokazano je da je legura posle novog dvostepenog termičkog starenja znatno otpornija prema naponskoj koroziji. Vrednosti zateznih karakteristika i žilavosti loma su slične za oba termička stanja legure. Razmatrani su procesi koji se odvijaju na vrhu naponsko-korozione prsline. Određen je uticaj temperature rastvora za ispitivanje na brzinu rasta prsline na platou. Određene su dve vrednosti prividne energije aktivacije.

AB  - The degree of preservation of iron artifacts depends on the type of underground environment and the type of corrosion products formed on their surface. This paper analyses the conditions of an archaeological find made of iron and originating from the Roman period and belonging to the collections of the Museum of Science and Technology in Belgrade. The radiographic method has been used to determine the quantity of non-corroded metal as well as to determine the presence of cracks and other defects in the artefact. The composition of the corrosion products has been analysed by the X-ray diffraction method (XRD). In addition to iron corrosion products (goethite α-FeO(OH) and magnetite Fe3O4), the presence of a significant quantity of akaganeite β-Fe8O8(OH)8Cl1.35, has been noticed on the artifact. The content of chloride, sulphate and other ions in the corrosion products has been determined by ion chromatography (IC). The analyses have pointed to the necessity of having artifacts treated in adequate solutions immediately after their excavation in order to eliminate chloride and sulphate anions. The aim of this paper is to determine the type of corrosion products and their influence on the corrosion behaviour ofr an archaeological artefact.
AB  - Koroziona postojanost eksponata od gvožđa zavisi od tipa podzemne sredine i vrste korozionih produkata koji se formiraju na njegovoj površini.

Radiografska metoda je korišćena za određivanje količine nekorodiralog metala, kao i prisustva prslina i drugih defekata u eksponatu. Sastav korozionih produkata je analiziran difrakcijom X-zraka (XRD). Pored korozionih produkata gvožđa (getita α-FeO(OH)I magnetita Fe3O4), uočena je značajna količina akagenita β-Fe8O8(OH)8Cl1.35 u sloju korozionih produkata. Metodom jonske hromatografije (IC) je određen sadržaj hloridnih, sulfatnih i drugih jona u korozionim produktima. Pomenute analize su ukazale na neophodnost tretmana arheološkog predmeta u odgovarajućem rastvoru za desalinaciju, neposredno posle iskopavanja, u cilju uklanjanja hloridnih i sulfatnih anjona. Cilj ovog rada je određivanje tipa korozionih produkata i njihovog uticaja na koroziono ponašanje arheološkog predmeta.

AB  - This paper analyzed  the conditions  for  the occurrence of corrosion  processes  on  historically  important  weapons  and  military equipment made of steel during the period in outdoor environment. A  considerable  attention  has  been  given  to  the  characteristics  of the most important corrosion products formed on the steel surface. The formation of akaganite,  β-FeOOH is a sign of active corrosion under a layer of corrosion products. The conditions that cause the formation and  regeneration of hydrochloric and sulphuric acid during  the exposure  to  the elements were analyzed. The most often applied methods of diagnostics and procedures of removing active corrosion anions (desalination) were described as well. The NaOH solution of certain pH values  still has  the most  important application  for  the desalination process. The procedures  for cleaning  the surface before the application of protective coatings and the application of chemicals  that  transform rust  into stable compounds were discussed. As protective coatings, different types of organic coatings  plated  on well-prepared  steel  surfaces were  used  and  sometimes  special  types  of waxes  as well. This  paper  presents  the results of the tests of corrosion products taken from the exhibits of weapons and military equipment  from  the Military Museum  in Begrade.

Razmotreni  su  postupci  čišćenja  površine  pre  nanošenja zaštitnih prevlaka  i primena sredstava koji  transformišu  rđu u hemijski stabilna jedinjenja. U svojstvu zaštitnih prevlaka se koriste različite vrste organskih prevlaka nanešenih na dobro pripremljenu površinu čelika, a nekada se takođe koriste specijalne vrste voska. U radu je prikazan deo rezultata ispitivanja korozionih produkata uzetih sa eksponata naoružanja i vojne opreme Vojnog muzeja u Beogradu.

Najveću  primenu još  uvek  ima  postupak  desalinacije  u  rastvoru  NaOH  određene  pH vrednosti.  Razmotreni  su  postupci  čišćenja  površine  pre  nanošenja zaštitnih prevlaka  i primena sredstava koji  transformišu  rđu u hemijski stabilna jedinjenja. U svojstvu zaštitnih prevlaka se koriste različite vrste organskih prevlaka nanešenih na dobro pripremljenu površinu čelika, a nekada se takođe koriste specijalne vrste voska. U radu je prikazan deo rezultata ispitivanja korozionih produkata uzetih sa eksponata naoružanja i vojne opreme Vojnog muzeja u Beogradu.",

AB  - This paper analyzes the state of the French Cannon 75/27 model 1911.
Déport made of steel. The amount of non-corroded materials, the presence
of cracks and other defects in the cannon were determined by the
radiographic method. The composition of corrosion products were
analyzed using diffraction of X-rays (XRD method). In addition to goethite
α-FeO(OH), lepidocrocite γ-FeO(OH) and magnetite Fe3O4, the presence
of akaganeite was observed in the corrosion products, β-Fe8O8(OH)8Cl1.35
which indicates the accelerated corrosion of the base metal. With the ion
chromatography method, the content of chloride, sulphate and other ions
in corrosion products were examined. On the basis of conducted
experiments, it can be concluded that it is necessary to treat the cannon in
appropriate solutions, as quickly as possible, to remove chloride and
sulphate ions.

AB  - One artefact of the archaeological cultural heritage from Roman period (IV century) that was found near Šabac in Serbia, was analysed. In corrosion products of the artefact (knife), dominant phases were goethite (α-FeOOH) and magnetite (Fe3O4). Presence of these types of corrosion products explains a good preservation of the base metal (iron) over the centuries and stability after excavation. Also, the less stable lepidocrocite (γ-FeOOH) and the phases that come from rocks and land surrounding environment (like SiO2) were identified in the corrosion products. Phases containing chloride ions (i.e. akaganéite) have not been detected in the corrosion products. This indirectly indicates that the amount chloride ions were rather low in underground exploitation conditions.

AB  - A degree of preservation of iron artefacts depends on the type of underground environment and the type of corrosion products formed on their surface. This paper analyses the conditions of an archaeological artefact made of iron, which was found to originate from the Roman period. The iron corrosion products, goethite, lepidocrocite and magnetite (determined by the X-ray diffraction method) have been noticed in the corrosion products of the artefact. The ion chromatography analysis has revealed chloride and sulphate anions, pointing to the necessity of having artefacts treated in adequate solutions immediately after their excavation. It has been found that the EDTA solution is very efficient in the process of desalination of the artefact. The aim of this study was to determine the influence of the corrosion product types and the effects of applying the EDTA solution, otherwise not commonly used for desalination of iron objects. This method was applied here due to the complex structures of the found archaeological artefacts and the presence of copper alloys besides iron. The aim of this paper is to determine the type of influence corrosion products have on an artefact and to determine the effect of desalination treatment.

The welded joints, by an X-ray radiographic method on possible presence of the welddefects, were tested. Grain size of the base metal and the welded joints, by applying an optical microscopywere determined. The existence of compatibility between the results for different electrochemical methods isshown. Heat affected zone (HAZ) of the austenitic stainless steel welded joints has shown significant degreeof sensitization. The corrosion potentials measurement method is simple, nondestructive method, that givesqualitative informations about degree of the sensitizations of the stainless steel. The double loopelectrochemical potentiokinetic method gives quantitative evidence about susceptibility of the stainless steelto intergranular corrosion. This method can be applied with some adaptation in field environments.
