中文摘要：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。
英文摘要：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.
