摘要

以Cu-Cr-Zr合金为基体

向其中添加Ni和Si

制备了Cu-Cr-Zr-Ni-Si合金

研究了固溶+时效处理对该合金的导电性能和显微硬度的影响。结果发现

Cu-0.6Cr-0.15Zr-2.8Ni-0.9Si合金的硬度（HV）快速下降

最低为95

电导率小幅降低

维持在9.28

0.44 MS/m之间

时效后合金电导率和硬度有较大提升。合金经960℃×2h固溶+550℃×1h时效

电导率为20.30 MS/m

硬度（HV）为273。

Abstract

Cu-Cr-Zr-Ni-Si alloy was prepared with Cu-Cr-Zr alloy as the matrix by adding Ni and Si element.Effects of solid solution and aging process on the conductivity and microhardness of the alloy prepared were analyzed.The results show that with the increase of solution temperature

the hardness of Cu-0.6Cr-0.15Zr-2.8Ni-0.9Si alloy is declined rapidly to 95 HV

and the conductivity is decreased slightly in range of 9.28

0.44MS/m.The conductivity and hardness of the alloy are improved greatly after aging treatment.After solution at 980 ℃for 2hand aging at 550 ℃for 1h

the conductivity can be increased to 20.30 MS/m

and the hardness can reach 273 HV.
