Alloy Ti – 50.2 at.% Ni for Actuators: Evolution of Structure and Shape Memory Effects During Post-Deformation Annealing. Part 2. Influence of Structure and Phase Transformation Special Features on Shape Memory Effects

The first part of the paper is devoted to regular features of microstructure formation and evolution of martensitic transformations during post-deformation annealing at 400 – 700°C. The second part presents results of a study of shape recovery characteristics reflecting their evolution as a function of the varying structural state and features of martensitic transformation during post-deformation annealing. Conditions for implementation of anomalously high characteristics of shape recovery under bending with nonisothermal loading are determined and analyzed.
