通过采用外加入Cr颗粒方制备Cu-5wt%Cr复合材料,研究了冷拔变形量和中间退火工艺对Cu-5wt%Cr复合材料中纤维组织形成过程及力学性能和导电性的影响。结果表明:随变形量的增加,Cr颗粒变形不均匀;退火使纤维发生弯曲、粗化、溶断等现象;材料的冷拔变形量与合理的中间退火工艺相组合,可得到强度和导电率的良好配合。 Cu-5wt% Cr composite was prepared by adding Cr particles into the Cu-5wt% Cr composite to study the effect of cold drawing deformation and intermediate annealing process on the microstructure, mechanical properties and electrical conductivity of Cu-5wt% Cr composite. The results show that the deformation of Cr particles is not uniform with the increase of deformation amount, and the bending, roughening and dissolving of fibers are caused by the annealing. The amount of cold drawing deformation of the material is combined with a reasonable intermediate annealing process to obtain the strength and conductivity Good cooperation.
