Abstract

The influence of Cr content, hot working, and heat treatment on the performance of Cu-Cr-Zr alloys was investigated. The as-cast microstructure of Cu-Cr-Zr alloys was uneven and micro-segregation. Fluctuations of the solid-phase solute are intensified and the degree of segregation is increased with the Cr content increasing. Cu-Cr-Zr alloys demonstrate combination properties of high strength and high conductivity after solution treatment, aging treatment. Good balance of strength and conductivity, which reach to 431.7 and 79.3% IACS respectively, was obtained in the Cu–0.86Cr–0.1Zr alloy.
