Abstract The influence of ausforming on the methods of tensile and impact fracture in a low alloy steel, has been studied. The ausforming produced austenite grains elongated parallel to the rolling direction and on subsequent quenching and tempering between 400 and 600° C, extensive networks of cementite particles formed along their boundaries. In this condition tensile failure occurred by the formation of longitudinal cracks along the prior austenite boundaries and these cracks joined together by transverse ductile tearing. On tempering above 600° C the boundary carbides coalesced and the matrix softened, and in this condition the steel possessed considerable resistance to transverse crack propagation.
