摘要
研究了不同时效工艺对Pd-Ag-Sn-In-Zn合金的力学性能、电学性能及显微组织和相结构的影响。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的析出强化,合金的电阻率变化主要受时效过程中再结晶和析出过程的综合影响。
The effect of aging treatment on the mechanical properties, the electrical conductivity and the microstructure of Pd-Ag-Sn-In-Zn alloy were studied. The result 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. The change of electrical resistivity was effected by the precipitation and the recrystallization.
