摘　　要：从合金元素、制备方法和析出相结构三方面综述了高强高导Cu-Cr-Zr系合金研究现状,探讨了该合金在研究、生产中存在的问题以及未来的发展趋势。固溶形变时效强化技术和快速凝固技术与常规固溶时效处理相比都能大大提高合金的综合性能,该类合金今后应向多元微合金化方向发展,尚待解决的主要问题是Zr、稀土等易烧损元素的熔炼控制。The recent developments from alloy elements, preparation process and precipitated phase in Cu-Cr-Zr system alloy were discussed. The problems during the research and the future development direction were also discussed. Compared with the conventional solution aging treatment, both the solution deformation aging strengthening technology and the fast solidification technology can enhance the overall performance of the Cu-Cr-Zr alloy. This kind of alloy will be supposed to develop to the multi-dimensional microalloy direction. The main problem is how to control the smelting of Zr and rare earth.
