摘要
Cu-Ag合金作为先进的导体材料,广泛应用于微电子、交通、航空航天及机械制造等工业领域。回顾了近年来高强高导Cu-Ag合金的主要研究进展。针对Cu-Ag合金的导电性和力学性能,主要从合金设计中的Ag成分设计、微合金化和加工工艺中的制备方法、热处理及变形处理等方面进行评述。分析了Cu-Ag合金的成分设计原则,比较了上述几种加工工艺的特点,并提出大塑性变形将会是一种非常有前景的制备高强高导Cu-Ag合金及其它合金的加工工艺。最后指出了现阶段研究中存在的问题及未来发展的趋势。
As an advanced conductive material, Cu-Ag alloy has been widely used in some fields, such as micro-electronics, transportation, aerospace and machinery manufacturing industries. The essay mainly focuses on the re search progress of high-strength and high-conductivity Cu-Ag alloy. Based on current researches on conductivity and mechanical property of Cu-Ag alloy, how to deal with Ag content in alloy design,micro-alloying, preparation method, heat treatment and the deformation process are reviewed. The choice of Ag content in alloy design is analyzed and the features of the above process are compared. It is proposed that severe plastic deformation will be a very promising pro- cessing technology to prepare high-strength and high-conductivity Cu-Ag alloys and other alloys. Finally, existing problems in recent research and future developing tendency are pointed out.
