摘　　要：采用无氧铜与电工纯铁为原材料运用冷轧复合工艺生产Cu/Fe/Cu复合件,分析了轧制压下率、退火温度对轧合件力学性能的影响,并运用金相显微镜、扫描电镜分析了组元的界面结合情况。结果表明,采用75%、80%压下率的冷轧工艺,且轧后采用700℃×30 min的退火工艺,可获得轧合件最佳的综合力学性能,其抗拉强度达385 MPa,抗剪切强度达358 MPa。CufFe/Cu composite was produced by cold rolling technology using oxygen copper and electrical pure iron. The effects of rolling reduction and annealing temperature on mechanical properties of composite were analyzed and optical microscopy and scanning electron microscopy （SEM） were utilized to reveal bonding condition. The results show that the optimal comprehensive mechanics performances were obtained under 75% -80%rolling reduction, annealing temperature at700℃ for 30 min, and the tensile strength and shear strength reach 385MPa and 358MPa respectively.
