Influences of Heat Treatment Process on Performances of High-strength and High-conductivity Cu-Cr-V-Zr-RE Alloy
Through heat treatment on the Cu-Cr-V-Zr-RE alloy,the influences of solution temperature,solution time,aging temperature and aging time on microhardness and electrical conductivity of the alloy were studied.The results show that the optimum solution treatment is 920℃×1h,aging treatment is 550℃×1h.A good comprehensive performance of the alloy can be obtained under the heat treatment process.The microhardness of the alloy is up to 134 HV and its electrical conductivity to 80.5%IACS.
