STRESS-AGING: A NEW TREATMENT FOR ALLOYS PART ONE: EFFECT ON STANDARD TENSILE PROPERTIES OF STAINLESS STEELS,
Abstract
Stress-Aging is a new treatment for alloys that results in concurrent increases of proportional limit, 0.1% offset yield strength, percent elongation and percent reduction of area. In general, for the three stainless steels (177PH, 17-4PH and AM355), the proportional limit (conservative measure of practical elasticity) may be increased by 100%, the 0.1% offset yield strength (a design factor) may be increased by 50,000 psi, with concurrent increases of 25-40% in percent elongation and 50% in percent reduction of area. Possible stress-aging reactions are discussed relative to the measured changes in properties that have been observed. Similar effects have been observed in other iron-base alloys and in copper-base and aluminum-base alloys. Ensuing reports will describe similar improvements currently being found in a typical gun steel and in four low-alloy ultra-high strength steels. (Author)
