THERMOMECHANICAL TREATMENTS APPLIED TO ULTRAHIGH-STRENGTH BAINITES.

Abstract

Retained austenite determinations were made in H11 which had been subjected to various thermal and thermomechanical treatments. It was found that up to 35% austenite is retained when bainite is formed at 550 F from either deformed or undeformed austenite. For tempering temperatures below 1000 F, retained austenite has a considerable effect on the yield strength of the mixed structure. The influence of retained austenite on the yield strength is not directly proportional to its volume percent. (Author)
