Processing for improved stress relaxation resistance in copper alloys exhibiting spinodal decomposition

摘要

A process for providing copper base alloys with a combination of high strength and high strength to ductility characteristics is disclosed. The alloys should be those copper alloys which exhibit continuous, homogeneous precipitation of coherent particles such as spinodal decomposition upon precipitation hardening. The alloys are hot worked, solution annealed and subjected to a controlled cooling to provide the desirable strength-ductility combinations.
