研究了退火温度对冷静液挤压铜包铝线材组织和性能的影响规律,在界面断裂形式分析的基础上探讨了其作用机理,结果表明:直径为6 mm的冷静液挤压态铜包铝线材合理的退火温度为350℃,低于200℃退火时,纯Cu包覆层只发生回复,复合线材的力学性能得以部分恢复;350℃退火时,铜层再结晶基本完成;复合线材的抗拉强度降到最低,延伸率则达到最高;400℃退火时,铜层晶粒开始长大,复合线材的延伸率开始劣化,界面结合强度随温度的变化呈先增加后降低的趋势,而界面的断裂则由低温退火时的铝基体塑性断裂转变为高温退火后Cu/Al界面的脆性断裂。

补充资料:铝-铜系铸造铝合金
分子式:
CAS号:
性质:以铜为主要合金元素的铸造铝合金。铜的含量范围在4%~14%。含铜9%以上的Al-Cu系合金,具有较好的铸造性能,可用于金属型铸造,并具有良好的抛光性能及电镀性能。但热处理强化效果不大,力学性能较低,主要用于装饰性零件。该系合金中具有重要应用价值的是由Al-5Cu合金基础上发展起来的高强度铸造铝合金和热强铸造铝合金。主要有Al-Cu-Si,Al-Cu-Mn,Al-Cu-Mg,Al-Cu-Ni,Al-Cu-RE等系列。Al-Cu系合金具有良好的切削加工性能和焊接性能。铸造性能较差,热裂、疏松倾向较大,需要合理的铸造工艺设计。
