The Effect of Microcracking in Martensite on the Deformation and Fracture Behavior of Fe-C Alloys and Commercial Steels.
Abstract
The effect of tempering on microcrack reduction was examined in an Fe-1.22C alloy. The major reduction occurred before transformation of the retained austenite and was attributed to tempering-induced plastic deformation. Fracture toughness of 52100 steel was measured according to ASTM E-399 and a transition from trans to intergranular fracture was noted with increasing austenitizing temperature. Auger-electron analysis showed high C and P present on intergranular fracture surfaces of carburized 8620 steel.
