ABSTRACT
A number of hypotheses on the mechanical behavior of shape memory alloys such as titanium nickelide in two‐step (martensitic and rhombohedral) phase transformations are formulated on the basis of experimental data. A system of relations linking stresses, strains, temperature, and phase composition in such transitions is proposed.
