INCREASING THE TOUGHNESS OF AFC 77 BY CONTROL OF RETAINED AUSTENITE CONTENT, AUSFORMING, AND STRAIN AGING,

Abstract

A high strength martensitic stainless steel, AFC 77, suffers from low fracture toughness in its highest strength conditions produced by tempering in the range 800 degrees F - 1100 degrees F. Three methods of improving toughness without loss of strength have been utilized to overcome this: control of retained austenite content, strain aging, and ausforming. (Author)
