摘 要: 通過合金成分和變形工藝研究， 制備了一種高強度高導電性的形變Cu-Fe原位復合材料。 實驗結(jié)果表明， 鐵含量越高， 強度越高， 導電性越低；加入少量鎂或鋯， 可提高強度， 但同時損失導電性。 在變形過程中， 加入適當?shù)闹虚g熱處理， 在改變強度不太大的前提下， 能大大提高導電性。 通過合理選擇合金成分和變形工藝流程，可制備不同強度和導電性等級要求的Cu-Fe原位復合材料。

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
