Study on the Microstructure and Properties of Cr-Zr-Cu Alloy
The effects of trace element Nb or Co and the cold deformation on the microstructure and properties of the Cr-Zr-Cu alloy have been investigated,in order to optimize the design of composition and the cold working process.In addi-tion,the process of aging treatment+depth cold treatment of the Cr-Zr-Cu alloy has also been investigated.The results show that the comprehensive performance of the Cr-Zr-Cu alloy with trace element Nb or Co added is good when the cry-ogenic deformation is about 50%,which exhibits high hardness and high electrical conductivity.Furthermore,the effect of deep-cooling treatment on the properties of Cr-Zr-Cu alloy containing trace amounts of element Nb or Co is not signifi-cant.
