The microstructural evolution, electrical conductivity, and mechanical properties of a cast Cu-6Cr alloy were investigated after being homogenized at 900 degrees C for 4 h, hot-rolled by 80%, solid solution treated at 940 degrees C for 2 h, and subjected to two steps of cold rolling and aging treatment. After several thermomechanical processes (HR + SST + CR + AT + CR + AT), the microhardness (155.2 HV), yield strength (439.8 MPa), and ultimate tensile strength (473.7 MPa) are significantly improved, and maintained a good electrical conductivity of 87.0 %IACS. Furthermore, under a load of 50 N...
