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℃ ,1h固溶和 450℃ ,2 0h时效后 ,抗拉强度为363MPa,屈服强度为 2 74MPa ,延伸率为 2 2 % ,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 50MPa,但电导率降低约 1 0 %IACS。
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 ℃, 1 h 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. [
