摘要(Abstract)：

通过显微硬度及相对电导率测试、光学显微镜和扫描电镜观察,研究了Cu-2.3Fe-0.05P-0.2Zn(C194)合金与Cu-2.3Fe-0.6P-0.2Zn合金冷轧态与时效态的组织与性能。结果表明:添加0.6%P元素,铜合金内部形成大量Fe2P相,一部分固溶到基体,一部分以颗粒形式弥散存在于合金内,尺寸可达10μm,后续热处理难以消除;Cu-2.3Fe-0.6P-0.2Zn合金的初始加工态性能优于C194合金,但基体中Fe溶质原子的浓度低,电导率上升速率变低;微米级Fe2P颗粒会激发再结晶,再结晶软化作用使得Cu-2.3Fe-0.6P-0.2Zn合金耐热性能低于C194合金。对于C194合金,P不宜过量。
