Properties of Large 7079 Aluminum Alloy Forgings in a Cryogenic Environment

Abstract

Large 7079-T652 hand forgings were evaluated for pump impeller and inducer applications in liquid oxygen/liquid hydrogen rocket engines. The results of mechanical property tests, reheat-treatment experiments, and micro structural studies are presented. The application of 7079 alloy in a cryogenic environment is discussed based upon the test results, and recommendations are made for metallurgical analysis of the more promising alloys.
