摘　　要：研究了室温低应变速率下大变形冷轧Cu80Fe20合金的显微组织和性能。结果表明,Cu80Fe20合金经过冷轧变形后富Fe相的显微组织呈现出明显的纤维状,显微硬度刚开始变形时上升很快,随着变形的增加,增加的幅度逐步降低;电导率随着轧制变形的增加而降低,当达到一定量的大变形后,电导率又有上升。The microstructure and properties of cold-rolled Cu80Fe20 alloy under low strain rate and large deformation were studied at room temperature.The results show that the microstructure of Cr-rich phases presents obvious fibre-shape,the microhardness increases continuously with the increase of rolling strain,the electrical conductivity decreases gradually with the increase of deformation strain,however,after deforming to certain degree,the electrical conductivity increases again.
