| 摘 要： | 研究了不同时效工艺对Cu-Zn-Cr合金的力学性能、电学性能及其显微组织的影响。结果表明：固溶－冷变形后合金的时效过程由过饱和固溶体的析出过程和基体的再结晶两个过程控制；合金高强度主要来源于加工硬化和第二相铬粒子的析出强化，合金的高导电性则主要来源于贫化后成份接近于铜锌固溶体的基体。

| Abstract: | The Effect of aging treatment on mechanical properties, electrical conductivity and microstructure of the alloy Cu Zn Cr were studied. The results show that the aging process of the alloy after solution treatment and cold deformation was controlled by both precipitation of the supersaturated solid solution and recrystallization of the matrix. The high strength comes from strain hardening and precipitation strengthening of the precipitated chromium particles. And the high electroconductivity is mainly due to the composition close to Cu Zn solid solution matrix after precipitation. |
