Cu-0.8Cr-0.1Nd(wt%) alloy was cast by median frequency vacuum induction furnace,afterward treated by solid solution,cold-deformed and aging.The microstructure,microhardness and conductivity in each process were investigated by optical microscopy,microhardness tester,and conductivity tester.The results indicate that the adding of Nd can obviously purify the Cu-matrix and refine its grains.With an increase of time of aging,the microhardness of Cu-0.8Cr-0.1Nd alloy first increased,then decreased,however the more cold-deformed of the alloy,the lower hardness was.Conductivity of the alloy after different cold-deformation increased notably,and then went smoothly.But the more the cold-deformed of the alloy,the higher conductivity it was.
