Influence of carburized surface on plastic properties of steel during tempering

Abstract

The specimen presents the investigation of plastic properties of carburized steel specimens during low tempering. Carburized specimens often deform during quenching, therefore, the principal aim of the experiment was to investigate one of the fixing ways of curved specimens - the bending of curved hardened specimens during tempering under the effect of transformation plasticity when even small internal load generates great deformations. The dependence between steel plasticity and carbon content at the tempering temperature was determined. The effect of asymmetrical carburization on steel transformation plasticity was examined evaluating the influence of structural compressive and tensile stress, which occurred because of volume mismatch.
