Abstract
A discrete dislocation-transformation model is used to analyze the response of an aggregate of ferritic and austenitic grains that can transform into martensite. In particular, the influence of the crystal orientation of the austenitic grains on the plastic and transformation behavior is studied. It is found that the austenitic crystal orientation has a stronger effect on the plastic behavior than on the transformation behavior. The transformation rate predicted by the discrete model only indicates a weak dependency on the austenitic crystal orientation.
