| Abstract Scope |
After the discovery of the Cr-Mn-Fe-Co-Ni equiatomic FCC solid-solution alloy with high strength and ductility, its derivative ternary and quaternary alloys have been the subject of extensive research. Early studies using polycrystals of various equiatomic FCC solid-solution alloys based on the Cr-Mn-Fe-Co-Ni alloy have suggested that the combination of elements is one of the most important factors that control the mechanical properties of these materials because both the highest strength and highest ductility are obtained for the Cr-Co-Ni ternary alloy. However, the detailed mechanism controlling the mechanical properties of these new FCC solid-solution alloys has not been fully clarified yet, partly because of the lack of fundamental experimental data obtained using single crystals. In the present study, we systematically investigated fundamental mechanical properties of a series of ternary equiatomic FCC solid-solution alloys based on the Cr-Mn-Fe-Co-Ni alloy by tension and compression tests of single crystals at low temperatures. |
