采用扫描电镜（SEM）、透射电镜（TEM）、材料测试系统（MTS）和电阻测量仪分别研究了合金元素Zr对变形处理Cu-Fe原位复合材料的结构、电阻率和强度的影响。实验结果表明，经中间热处理冷拉至拉伸应变η= 7.57时，Cu-11.5% Fe- zr丝的极限拉伸强度（UTS）和电导率分别为824 MPa和61.4% IACS, Cu-11.5% Fe丝的极限拉伸强度和电导率分别为752 MPa和64.6% IACS。Zr的掺入可以提高Cu-Fe复合材料的热稳定性。在较高的退火温度下（300℃以上），Cu-Fe- zr丝的强度下降并不比Cu-Fe丝快。
Effect of doping with alloying element Zr on the structure, the electrical resistivity and the strength of deformation-processed Cu-Fe in-situ composites were studied respectively by scanning electron microscope (SEM), transmission electronic microscope (TEM), material test system (MTS) and resistance measuring apparatus. The experimental results show that the ultimate tensile strength (UTS) and the conductivity of Cu-11.5% Fe-Zr wire cold drawn to the drawing strainη= 7.57 with intermediate heat treatments were observed to be 824 MPa and 61.4% IACS respectively, and those of Cu-11.5% Fe were 752 MPa and 64.6% IACS. Doping Zr can improve the thermal stability of Cu-Fe composites. The strength of Cu-Fe-Zr wire does not drop more rapidly at higher annealing temperatures (above 300°C) than that of Cu-Fe wire.
