摘要

Cu-2Ti-0.3Zr and Cu-2Ti-0.3Zr-0.2La alloys were prepared by vacuum melting, and their mechanical properties and conductivity were measured after aging treatment. Both alloys were aged at 450 °C for 30 min to obtain optimum properties, and the microhardness of the Cu-Ti-Zr-La alloy increased by 8.5
