Microstructure evolution and properties of a Cu–Cr–Zr alloy with high strength and high conductivity

Effects on microstructure evolution, mechanical and electrical properties of a Cu–Cr–Zr–Ni–Si–Ti alloy via multi-stage rolling and aging were investigated in details. The results showed that the optimal comprehensive performance of tensile strength (649 MPa) and electrical conductivity (65.5 %IACS) was obtained by three-stage rolling and aging (primary 80% room-temperature rolling (RTR) and aging at 450 °C for 2 h + secondary 60%RTR and aging at...
