摘要

研究了刚性铜铝复合接触线用银铜合金的抗软化性及再结晶

硬度测试、组织和静态再结晶动力学的分析结果表明

银铜合金的软化温度约为390℃

再结晶温度为350～450℃。银铜合金退火过程中发生再结晶的激活能为77.68kJ.mol-1;350℃、390℃退火时的再结晶完成时间分别约为414.4、167.7min。

Abstract

Softening and recrystallization of Cu-Ag alloy for Cu cladding Al contact wire were analyzed by hardness testing

microstructure and static recrystallization kinetics.The results indicate that softening temperature of the Cu-Ag alloy is approximately 390℃

and recrystallization temperature is in range of 350～450 ℃.Activation energy of recrystallization is calculated to be 77.68kJ/mol during annealing process.Completed time of recrystallization makes about 414.4

167.7 min with annealing at 350 ℃ and at 390℃.
