Abstract

The influence of preliminary plastic deformation on the shape memory effect initiated by reorientation of structural domains has been investigated. Experiment data have shown that the recovery factor decreases with the increase of plastic deformation under the power law. It is connected with the two-way shape memory established by the deformation. Besides, it was obtained that the hardening of TiNi alloy in an austenitic state is not inherited by the martensite phase.
