摘要: 介绍了铜铬合金的性能、应用及该材料现有的制备方法。提出了采用机械合金化制粉，进而进行爆炸烧结和后续热扩散处理的制取铜铬合金的方法，并初步进行了实验研究。研究结果表明，采用上述方法可以制造出高密度、组织均匀、晶粒细化的CuCr合金。在wCu∶wCr＝1∶1的条件下，可制出密度大于95%理论密度、硬度HV大于217的具有纳米晶粒的CuCr合金，明显优于热等静压、熔渗和电弧熔炼产品。

Abstract: This paper introduces the performance, applications and existing producing methods of CuCr alloy. The method making powder by mechanical alloying is brought forward. Getting CuCr alloy by explosive sintering and thermal diffusion disposal are studied some primary experiments were done. The results show that CuCr alloy with high density, even structure, thinning crystalloid are obtained. On condition of Cu∶Cr=50∶50, CuCr alloy with nanometer crystalloid, density95% TD, rigidity217HV can be obtained which obviously exceeds the production by hot-isostatic pressing, infiltration and arc melting.
