摘要：

通过室温下低应变速率大变形冷轧Cu88Fe12合金，研究了其显微组织和性能的变化。研究结果表明，经过冷轧变形后Cu88Fe12合金富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，电导率又有所上升。

The microstructures and properties of heavily cold rolled Cu88Fe12 alloys at low strain rate were studied at room temperature. The experiment results show that the microstructure of Fe\|rich phases are deformed to ribbons filaments, the microhardness increases continuously with the increasing of rolling strain, the electrical conductivity first decreases gradually with the deformation strain, however, after deforming to certain degree, the electrical conductivity increases again.
