Abstract

Microstructure and properties of Cu-0.8Cr-0.1Zr alloy under different processing and heat treatment were investigated

and the optimized processing parameters were presented through comparing the properties and structure.The results show that Cu-0.8Cr-0.1Zr alloy exhibits good performance after hot extrusion deformation and solution treatment at 980 ℃ for 40 min+aging at 460 ℃ for 3 h

and micro-hardness and electrical conductivity reach HV0.2131

49.01 MS/m

respectively.
