Metal Science and Treatment of Metals| Summary: | High-entropy AlCoFeCrVNi and AlCoFeCrVTi alloys were obtained by mechanical alloying and sintering, and it was shown that after mechanical alloying alloys consist mainly of BCC solid solutionі and insignificant amount of FCC solid solutionі, which are in a nanostructural state. After sintering in a vacuum the alloys consist of FCC solid solutions and precipitates of intermetallic and carbide phases. After sintering under high pressure alloys consist of FCC and BCC solid solutions and the FCC solid solution is a predominant phase in both alloys. Also sintering under high pressure allows keeping nanostructural state in AlCoFeCrVNi and AlCoFeCrVTi alloys and increased microhardness. |
