摘要(Abstract)：

高Ag含量Cu-Ag合金因具有突出的电学和力学性能、良好的导电与强度匹配性和优异的冷加工变形能力等特点，在强磁场和电子信息领域核心部件上具有良好的应用前景，如脉冲/稳态强磁场装置水冷磁体和超大规模集成电路引线框架。本文主要基于国内外研究者关于高Ag含量Cu-Ag合金微观组织、强度和导电性能等方面的研究，从合金成分设计、制备工艺、变形加工工艺和强化机理4个方面对Cu-Ag合金制备研究进行综述。通过对比分析不同成分Cu-Ag合金微观组织特征、不同加工工艺的特点和典型Cu-Ag合金强化机理，提出了当前存在的问题，为制备宽幅面、大尺寸超高强高导高Ag含量Cu-Ag合金板材提供借鉴和思路。
