AB  - Legure nikla se koriste na povišenim temperaturama i pritiscima, odnosno pod najnepovoljnijim radnim uslovima, tako da je preciznost ispitivanja od posebnog značaja. Tendencija usavršavanja postojećih legura predstavlja posebno interesovanje u tehničkom i naučnom svetu. Na osnovu teorijskih postavki, analize eksperimentalnih rezultata, ustanovljeno je da na kvalitet legura nikla znatno utiču promene u strukturi koje nastaju u toku eksploatacije. Odgovarajućim termomehaničkim režimima eliminisani su defekti u materijalu nastali tokom eksploatacije, a primenom savremenih tehnika utvrđeni optimalni parametri procesa. Poseban značaj u istraživanju imaju fino strukturna ispitivanja vezana za optičku i elektronsku mikroskopiju koja su primenjena na legurama nikla i prikazana u ovom radu.
AB  - Nickel alloys are used on elevated temperatures and pressures, ie under the most unfavorable working conditions, so the accuracy of the test is of particular importance. The tendency to improve existing alloys is especially interest in the technical and scientific world. Based on theoretical settings, the analyzes of experimental results, it was established that the quality of nickel alloys are significantly influenced by changes in the structure that arise during the exploitation. The corresponding thermomechanical regimes eliminated defects in the material incurred during the exploitation, and the application of modern techniques determined by optimal process parameters. Special importance in the research have fine structural tests related to optical and electron microscopy applied to nickel alloys and presented in this paper.

AB  - Nickel-base superalloys are an important class of engineering materials designed for high - temperature applications such as aero-engine components. Good corrosion resistance, optimal thermal properties, strength coupled with ductility, creep and fatigue resistance, as well as optimal impact and wear resistance are the main requirements for a satisfactory function in such severe environments at high temperatures. Lasers have been used for high precision material processing in micro- and nanomanufacturing operations due to the specific nature of the light that they emit, such as the high intensity and the possibility of controlled surface modification. In the last few decades a lot of attention was paid to surface modifications of different metals and their alloys by various types of laser light. Treatment of superalloys’ surfaces with laser light can induce the changes in the microstructure which result in improved mechanical properties of the material.
In this work, the process of interaction is related to exposure of nickel superalloy M-252 to femtosecond laser beam. The effect of the laser beams on the surface of the multicomponent alloys is performed by different pulse energies and different exposition time. The changes in the microstructure, depending on the parameters of the laser beam, are identified by the scanning electron microscope (SEM) and energy-dispersive spectrometry (EDS), and the mean grain size was measured by the method of the circle. The aim of the study was to optimize the parameters of laser treatment to reach the microstructure with the favourably affects for the surface quality.

AB  - Energetske tehnologije predstavljaju integralni deo industrijskog nasleđa u okviru Evropskog puta industrijske baštine, koji obuhvata preko osam stotina gradova i mesta u 29 evropskih zemalja. Tema ove rute pokazuje ulogu industrijalizacije u ukupnoj evropskoj savremenoj istoriji, a način tretiranja industrijskih objekata čija je namena prevaziđena, govori o odnosu različitih evropskih sredina prema sostvenoj industrijskoj kulturi. Ovo istraživanje bavi se stanjem  energetskog industrijskog nasleđa u Srbiji, kao i mogućnošću njegovog inkorporiranja u Evropski put industrijske baštine, sa posebnim osvrtom na heritološke zahteve u procesu očuvanja.
