摘 要: 通过合金成分和变形工艺研究， 制备了一种高强度高导电性的形变Cu-Fe原位复合材料。 实验结果表明， 铁含量越高， 强度越高， 导电性越低；加入少量镁或锆， 可提高强度， 但同时损失导电性。 在变形过程中， 加入适当的中间热处理， 在改变强度不太大的前提下， 能大大提高导电性。 通过合理选择合金成分和变形工艺流程，可制备不同强度和导电性等级要求的Cu-Fe原位复合材料。

Abstract: In order to develop the high strength and high electrical conductivity deformation-processed Cu-Fe in situ composites, the alloy composition and deformation route were studied. The results indicated that the strength increasing and electrical conductivity decreasing with increasing Fe content. Addition of a little of Mg or Zr , the strength can be increased and the electrical conductivity is losing. But the effects of addition of a little of Mg or Zr is little. By heat treating in wire drawing, the electrical conductivity can be increased greatly. Optimizing the alloy composition and deformation route, the good combination of the strength and electrical conductivity of Cu-Fe in situ composites can be obtained.
Key words: Cu-Fe in situ composites; strength; electrical conductivity
