Abstract
The retrogression and reaging (RRA) heat-treatment process and recent developments in high-strength 7xxx series aluminum alloys are summarized in this article. The results of experimental work indicate that RRA 7249 aluminum has the strength equivalent to or greater than 7249-T6 and superior corrosion resistance. This work is the result of collaborative efforts between the U.S. Navy and Loyola Marymount University.
