C19210 is one of the Cu-Fe-P alloys extensively employed in the electronics industry. In order to enhance strength and electrical conductivity of the alloy, thermo-mechanical treatment was applied. In this work, the influences of deformation heat treatment on the mechanical properties, electrical conductivity, and microstructure of C19210 were investigated. Results showed that the optimal properties, including a Vickers hardness of 134HV, tensile strength of 445 MPa, electrical conductivity of 88.4%IACS, and elongation of 16.3%, can be achieved through an optimized combinatorial process: solution treatment at 900 ℃ for 120 min, primary cold rolling (80% reduction) with aging at 450 ℃ for 240 min, followed by secondary cold rolling (50% reduction) and aging at 450 ℃ for 60 min. Microstructural observations revealed that combined effects of precipitation strengthening from dispersed precipitates and grain refinement from fine recrystallized grains contributed to the improvement of strength and electrical conductivity. These findings provided a theoretical and practical foundation for optimizing the performance and engineering application of Cu-Fe-P alloys.

C19210合金属Cu-Fe-P系合金，主要应用于电子工业领域。为提高C19210合金的综合性能（强度和电导率），对其进行形变热处理，研究形变热处理对合金力学性能、电导率以及显微组织的影响规律。结果表明，C19210合金经900 ℃×120 min固溶处理后，采用一次冷轧（80%变形）+450 ℃×240 min时效，再经二次冷轧（50%变形）+450 ℃×60 min时效工艺处理，综合性能达到最佳，其维氏硬度为134HV，抗拉强度为445 MPa，电导率为88.4%IACS，伸长率为16.3%。显微组织分析发现，经过形变热处理，合金可获得细小再结晶组织和大量弥散分布的细小析出相，析出强化与细晶强化两者共同作用，使合金具有良好的电导率和强度。本研究为Cu-Fe-P系合金的性能优化与工程应用提供了理论依据和工艺指导。
