000015322 520__ $$2eng$$aWe have studied stress induced martensitic transformations in nanocrystalline materials using a Ginzburg Landau/phase field approach. We incorporate the effect of grain boundary energy in our simulations and show that if the grain boundary energy of the martensite phase is larger than that of austenite, a local suppression of the transformation can occur at the grain boundaries. For small grain sizes, this leads to an overall suppression of the transformation, which also reflects in the stress-strain curve. In accordance with experimental observations, a reduction of hysteresis associated with the superelastic stress strain curves is also observed.
