摘　　要：在真空感应炉熔炼得到Cu-0.2Cr-0.1Ag合金,研究了该合金在不同加工条件下的组织、强度和导电性变化。研究表明,通过固溶强化、时效强化和形变强化等手段的配合,可以获得高强度、高导电性的Cu-0.2Cr-0.1Ag合金。固溶、时效处理后的合金导电率达91%IACS,伸长率为37.4%。在固溶后加入冷变形,然后再时效,可以使强度提高84MPa,而导电率不发生变化,再继续冷变形可以使强度提高到556MPa。The Cu-0.2Cr-0.1Ag alloy was founded in vacuum induction furnace.The microstructures and variations of properties of this kind copper alloy under different processing and heat treatment were researched.The results show that the high strength and high conductivity Cu-0.2Cr-0.1Ag alloy can be obtained to use combined strengthening techniques of solid solution,aging and strain hardening.The conductivity and elongation of Cu-0.2Cr-0.1Ag alloy can reach to 91% IACS and 37.4% after solution and aging treatment.The strength of the alloy enhances 84 MPa and the conductivity is not changed after introducing cold rolling between the processes of solution and aging,then the strength of alloy can be increased to 556 MPa by subsequent cold deformation.
