| 摘 要： | 利用金相显微镜和万能材料试验机,通过界面组织观察和力学性能测试,系统研究了铜／铝／铜冷轧复合薄带的热处理工艺,并讨论了热处理工艺参数对铜铝冷轧复合薄带界面组织和力学性能的影响规律．通过研究,得出如下结论：随退火温度升高或保温时间的延长,复合带强度降低,塑性增强;退火后复合带界面宽度为2-5／μm,界面有脆性化合物CuAl2,CuAI和Cu9A14生成;410℃退火,保温10min时复合带综合性能最佳,为复合薄带的最佳热处理工艺。

| Abstract: | By using a metallograph and a universal material testing machine to observe the interface microstructure of Cu/Al composite thin plates and test their mechanical properties,the effect of heat treatment parameters on them was investegated. It is concluded that the strength of the composite plates decreases and their plasticity increases with increasing the annealed temperature or holding time.The interface width of the composite plates is 2～5 μm after annealing,with brittle compounds(CuAl2,CuAl and Cu9Al4) observed.The composite plates annealed at 410 ℃ for 10 min exhibit the optimal balance of mechanical properties, i.e.,heating up to 410 ℃ then holding 10 min is an optimal annealing schedule. |
