摘要: 制备了CuCr和CuCrZr二种合金板材，研究了不同热处理工艺对合金的显微组织、力学性能和导电性能的影响。结果表明，在本实验条件下， Cu0.5Cr合金经960 ℃, 1 h固溶和450 ℃, 20 h时效后，抗拉强度为363 MPa，屈服强度为274 MPa，延伸率为22%，电导率达81%IACS；添加微量Zr到Cu0.5Cr合金中，在不降低合金延伸率情况下，合金强度可提高50 MPa，但电导率降低约10%IACS。

Abstract:Cu0.5Cr and Cu0.5Cr0.2Zr alloy plates were prepared. The effects of heat treatment on microstructure, mechanical properties and electrical conductivity have been studied. The results show that under 960 ℃, 1h solution treating and 450 ℃, 20 h aging condition, the tensile strength, yield strength, elongation and electrical conductivity of Cu0.5Cr alloy can reach 363 MPa, 274 MPa, 22% and 81%IACS respectively. Adding 0.2%Zr to Cu0.5Cr alloy, the tensile strength and yield strength of the alloy increase by about 50 MPa. However, under this condition the electrical conductivity of the alloy decreases by 10%IACS.
