Abstract

This solution heat treatment of a Cu-Cr-Zr alloy was examined. The alloy was found to contain precipitates rich in chromium and precipitates rich in Cr-Zr-P. Some of the precipitates were in the form of stringers. Solution heat treatment at 1000 or 1050circC for periods up to 24 h caused few, if any, of the precipitates to go into solution. This was thought to be due to the relatively coarse nature of the precipitates. However, by cold rolling the as-received alloy prior to solution heat treatment, solution of the precipitates was greatly enhanced. This was thought to be because the particles deformed and broke up during rolling. As expected, grain growth also occurred.
