摘要
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。
Cu-Ag alloys with high Ag content have good application prospects in the core components of high magnetic field and electronic information field due to its excellent electrical and mechanical properties, good matching between electrical conductivity and strength, and excellent cold working deformation ability, such as conductor materials for high pulse/steady state magnetic field devices and lead frames for very large-scale integrated circuits. Based on the research of domestic and foreign researchers on the microstructure, strength and electrical conductivity of Cu-Ag alloys with high Ag content, this paper summarizes the preparation of Cu-Ag alloys from four aspects: alloy composition design, preparation process, deformation processing technology and strengthening mechanism. By comparing and analyzing the microstructure characteristics of Cu-Ag alloys with different components, the characteristics of different processing processes and the strengthening mechanism of typical Cu-Ag alloys, the existing problems are put forward, which provides reference and ideas for the preparation of Cu-Ag alloy plates with wide width, large size, ultra-high strength and high conductivity.
