Transformation Texture in Deformed Stainless Steel

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

Abstract

In an elegant experimental study on an austenitic stainless steel, Gey et al. [1] found that not all of the 24 possible crystallographic variants of martensite (α ′ ) formed when the alloy underwent transformation during tensile deformation. The selection of particular variants was demonstrated by comparing calculated pole figures containing poles from all 24 α ′ orientations against measured pole–figures. This variant selection was particularly noticeable in austenite (γ) grains belonging to the Goss and Cube components of texture, which transformed to smaller fractions of martensite. This is presumably because the early stages of transformation are dominated by the α ′ variants most favoured by the external stress. The selection process was explained qualitatively by associating the martensite with the slip systems that have the greatest Schmidt factors, although even on the “activated ” {111}γ planes, only a fraction of the possible variants were found. We show in this note that the observed transformation textures can be calculated by considering the interaction of the applied stress with the martensite plates, based on a self–consistent set of crystallographic parameters
