Abstract

It is proposed on the basis of equilibrium thermodynamics that the microstructure of a stress-induced twinned martensite plate adheres to the criterion of mechanical free energy minimisation, rather than that of invariant plane deformation. This lowers the predicted transformation stress. To demonstrate the proposal, an Fe-Pd shape memory alloy is considered. © 2003 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
