HIGH STRENGTH-HIGH CONDUCTIVITY Cu-Cr COMPOSITES PRODUCED BY SOLIDIFICATION/MECHANICAL REDUCTION

摘要

A Cu-Cr melt is solidified to form a two phase, cast body (e.g., an ingot) and the body is mechanically reduced to form an "in-situ" composite. The body in the solidified condition and/or the deformed condition is subjected to temperature and time at temperature conditions effective to precipitate dissolved Cr from the Cu matrix to improve the electrical conductivity of the composite.
