设计了一种经冷加工和时效强化的新型高强高导Cu-Fe-P-B-Ce合金。测试了Cu-Fe-P和Cu-Fe-P-B-Ce合金的力学性能和电导率，并利用光学显微镜和透射电镜分析了试样的显微组织。结果表明，微量B和Ce的加入可显著提高Cu-Fe-P合金的再结晶温度。因此，采用沉淀硬化和冷加工硬化相结合的方法，可以获得较好的强化效果。该新型Cu-Fe-P-B-Ce合金具有优良的综合性能，其抗拉强度（σB）为509 MPa，延伸率（δ）为16%，电导率为80% IACS。
A new high-strength and high-conductivity Cu–Fe–P–B–Ce alloy strengthened by cold working and aging was designed. The mechanical properties and electrical conductivity of Cu–Fe–P and Cu–Fe–P–B–Ce alloys were measured, and the microstructures of the samples were analyzed with optical microscope and by transmission electron microscopy. Results showed that the recrystallization temperature of Cu–Fe–P alloy was greatly raised by adding trace B and Ce. Thus, the good strengthening effect processed by both precipitation hardening and cold working hardening was obtained. This novel Cu–Fe–P–B–Ce alloy exhibits excellent combination property that the tensile strength (σb) is 509MPa, the elongation (δ) is 16% and the conductivity is 80% IACS.
