【摘要】 研究了稀土金属Y不同添加量和不同固溶时效处理工艺对Cu0 8Cr合金硬度和导电率的影响。结果表明 ,铸态Cu0 8Cr合金的硬度随Y含量的增加而升高 ;经过不同固溶时效后 ,硬度出现波动 ,其中Cu0 8Cr0 4Y可获得最高硬度。过量的Y能增加硬度 ,但会降低导电率 ,经固溶时效处理后导电率最高的合金为Cu0 8Cr0 1Y。更多还原

【Abstract】 The effects of Y addition and different solution and aging processes on hardness and electrical conductivity of Cu-Cr alloys were studied.The results show that the hardness of Cu0.8Cr alloy as casting is enhanced with the increasing of Y.After different processes of solution-aging,the hardnesses of alloys are fluctuating,and the hardness of Cu0.8Cr0.4Y is the highest.More Y can increase hardness of the alloy but reduce electrical conductivity.After solution-aging,the electrical conductivity of Cu0.8Cr0.1Y reaches the peak point.更多还原
