摘要(Abstract)：

采用光学显微镜、硬度和电导率测试等方法研究了不同变形量Cu-0.1Ag铜银合金不同温度退火下的组织性能变化规律及再结晶特征。结果表明:随变形量增加,再结晶后晶粒更加细小;硬度在回复阶段几乎不变或略有上升,在再结晶阶段直线下降,再结晶完成后硬度趋于定值。退火温度越高,硬度下降较快,再结晶速率较快。电导率在回复与再结晶过程中显著上升,再结晶完成后电导率趋于定值。室温拉拔变形量26%及50%Cu-0.1Ag合金的再结晶激活能分别为82 k J/mol及69.6 k J/mol,在400~500℃范围内完成再结晶所需时间与温度函数关系分别为lnt=8.2×104/RT-7.56和lnt=6.96×104/RT-6.04。
