摘　　要：对一种含微量Al熔渗态Cu Cr合金直接进行不同温度的时效处理,测试了时效处理前后Cu Cr合金的热扩散系数和电导率。结果表明,直接时效处理能提高熔渗态Cu Cr合金热扩散系数和电导率,经500℃×2 h时效处理后,Cu Cr合金可获得较高的热扩散系数和电导率,其值分别为0.418×10-4 m2·s-1和16.02 MS·m-1,较熔渗态的合金分别提高了12.37%和15.75%。Aging treatment with different temperature was carried out on an infiltrated Cu Cr alloy with trace Al, and the thermal diffusion coefficient and electric conductivity of the alloy before and after aging treatment were measured. The results show that the aging treatment can increase the thermal diffusion coefficient and electric conductivity of the alloy, the alloy aging at 500 ℃ for 2 h possesses a higher thermal diffusion coefficient and electric conductivity, and they are 0.418×10^-4 m^2·s^-1 and 16.02 MS·m^-1, and it is compared with the infiltrated alloy, the thermal diffusion coefficient and electric conductivity increase by 12.37% and 15.75%, respectively.
