Abstract: In high temperature shape memory alloys, the inelastic deformation mechanism is a combination of the transformation strain, viscoplastic strain in austenitic and martensitic phases, and transformation-induced plasticity. The latter is a consequence of the effect of austenite↔martensite transformation on the dislocation dynamics. In this study, the effect of the martensitic plates in microstructure, in the case of the internal stress field, is shown by a theoretical solution of the martensitic inclusions. The one-dimensional phenomenological continuum model is presented to predict the macroscopic behavior of a sample high temperature shape memory alloy by making a link between the internal stress field of the microstructure and the phenomenological model.
