AB  - Even though it has been in use for a very long time, the high chromium white cast iron (HCWCI) still triggers scientists  due to its outstanding wear resistance. Besides its well-known as-cast usage, it can be used as a coating material, as well.  HCWCI owes this feature due to the presence of carbides in microstructure, which depends on the composition and heat  treatment regime. This investigation was conducted on two HCWCI alloys, where in addition to chromium, the second  important alloying element is molybdenum (Mo). Apart from other alloying elements, HCWCI_1 is alloyed with 24.48%  Cr and 1.32% Mo, while HCWCI_2 contains 14.11% Cr and 2.47% Mo. The comprehensive microstructural  characterization was carried out on as-cast samples and samples obtained after quenching (at -196oC) and/or quenching  followed by tempering (at 250oC). Important microstructure indicators are: the stability of austenite, the ratio of microconstituents (especially different types of carbides), as well as their arrangement and morphology, so they are revealed  and discussed in relation to the influencing mechanical properties.

AB  - Determination of the extractive behavior of ionic species from lateritic ore leachates is complex, since the leachates are pregnant with tens of different ions in, as a rule, multiple oxide states. To examine the possible pathways of intrinsic electrochemical extraction of the crucial elements Ni and Co, it was necessary to make model solutions of these elements and to subject them to electrochemical examination techniques in order to obtain a benchmark. Beside Ni and Co, the model system for Fe had to be evaluated. Iron, as a dominant ore component by far, is the main interfering factor in the extraction processes of Ni and Co in rather low amounts from leaching solution. The leachate examination results were compared to separate model solutions, as well as to their combinations in concentrations and to pH values comparable to those of the leachate. The separation of the leachate components was initially performed by continuous increase in pH upon leaching with NaOH solution, and afterwards the pH-adjusted solutions were subjected to electrochemical investigation. With the purpose of connecting and quantifying the visual changes in leachate upon increase in pH, conductometric measurements were performed. Reactions of oxidation/precipitations were indicated, which led to the essential Fe removal by precipitation. Resulting solutions were found suitable for Ni and Co electrochemical extraction.
