摘要

The CuCr25 alloys prepared by vacuum induction melting (VIM) were investigated. The experimental results show that W and Ni had significant influence on the microstructure of CuCr25 alloys. For CuCr25Ni0.5 and CuCr25W1 alloys, the Cr phase was dramatically refined and presented nodular morphology. W could increase the breakdown strength of CuCr25. The electric conductivity of CuCr25Ni0.5 decreased, but still reached the level of conventional CuCr alloys. The other properties of CuCr25Ni0.5 and CuCr25W1 alloys did not degrade.
