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。
The effects of rolling reduction rate and annealing temperature on the mechanical properties of the rolling-in parts were analyzed by using cold-rolled composite process with oxygen-free copper and pure iron as raw materials. Electron microscopy analysis of the component interface combination. The results show that the best mechanical properties of rolled parts are obtained with the cold rolling at 75% and 80% reduction rates and the annealing at 700 ℃ for 30 min after rolling. The tensile strength reaches 385 MPa, Shear strength up to 358 MPa.
