A Variant Selection Model for the Prediction of Fcc-To-Bcc Transformation Textures

Received14 Feb 1996

Abstract

In the present work, a simple model is described for the prediction of fcc-to-bcc transformation textures. It employs a discrete distribution of orientations and is based on the Kurdjumov-Sachs relationship for the γ-to-α transformation. An important feature of the model involves the variant selection rule, which assumes that nucleation is favoured according to a slip system based variant selection criterion. Subsequent selective growth involves a transformation work rule based on the Bain strains and the presence of an internal stress field. The transformation texture predicted from an experimental 95% cold rolled Ni-30wt%Co alloy texture is compared to experimental martensite textures for both a Nb-microalloyed steel and a Fe-30%Ni alloy. The predicted texture displays better agreement with the steel data.
