Transformation Texture in Deformed Stainless Steel

Saurabh Kundu and H. K. D. H. Bhadeshia


The development of transformation texture in a deformed austenitic stainless steel has been modelled using the crystallographic theory of martensite, and the interaction of martensite with the applied stress. It has thus been possible to explain published data on variant selection in martensite induced to form during the tensile deformation of austenitic stainless steel.
