摘 要：By introducing Cu, AlCoCrFeNiCux （x values in molar ratio, x = 0, 0.1, 0.5, 1.0, 1.5, 2.0, and 2.5） alloys were designed and prepared. The effects of Cu on microstructure and properties of Al Co Cr Fe Ni alloy were investigated. The introduction of Cu results in the formation of Cu-rich FCC solid solution phase when Cu content is low.There are two FCC solid solution phases, i.e., Cu-rich FCC solid solution phase and phase transformation-induced FCC solid solution phase, when the Cu content is more than 1.0. Both the yield stress and plastic strain of alloy show a turning point when the Cu content is 0.5. Among the seven alloys, Cu0.5 alloy exhibits the largest yield stress of 1187 MPa and the lowest plastic strain of 16.01 %.
