中文摘要：通过添加Fe、P和Zn研究了C194铜合金的铸态组织，设计并选择合理的加工工艺(熔炼、铸造、热轧、固溶处理、冷扎变形、时效处理)来获得导电性能良好的C194引线框架铜合金。结果表明，在时效处理前进行冷轧， 可有效提高C194引线框架铜合金的导电性。
英文摘要：The microstructure of as-cast C194 copper alloy was studied after adding Fe, P and Zn. Fine electric conductivity of C194 copper alloy for leading frame was obtained through adjusting the process, including melting, casting, hot rolling, solution treatment, deformation, cold-rolling and aging. The results show that the cold rolling before aging treatment can enhance the conductivity of C194 copper alloy.
