EFFECT OF MECHANICAL AND THERMAL PROCESSING ON HIGH-STRENGTH STEELS

Abstract

Identifer : C HARPY IMP CT TEST. The effect of prestraining and gi g on the mechanical properties of H11 was investiga ed for 2 other conditions of temper (600 and 1050 F) These temperi g t mperatures produce higher toughness level tha was obtained for specimens tempered at 975 F. The effect of the strain aging treatments of specimens tempered at 600 F showed much the same trend as for pecimens temper d a 75 F. However, th mag itu es of the changes were much greater. Similar re ult w re obtained for speci t p r d at 1050 F E CEPT T AT THE MAGNITUDES OF E C ANGES WERE CONSIDERABLY LESS THAN THAT OBTAINED ON SPECIMENS TEMPERED AT >) F. Significant incr ases in yield strength were obtained at higher than expected toughness levels. Determinations of retained austenite and some observations of micro tructures for the various tempered conditions are presented. (Author)
