Metal Science and Treatment of Metals| Резюме: | The results of the synthesis high entropy AlCoNiFeCrTi alloy from elemental powder mixture by short-term mechanical alloying (MA) method in high energy planetary mill and subsequent annealing at 1200 °С for 1 hour were shown. Phase and structural transformations were studied by X-ray diffraction and microstructural analysis with MA and after annealing alloys. Synthesized high entropy AlCoNiFeCrTi alloys consist of BCC and FCC solid solutions, intermetallic compounds AlTiСо2, Cr0,99Fe1,01 (s-phase) and TiC depending on time MA. The microhardness of HV alloys after annealing is 9–10 GPa. |
