摘要：
The effect of the microstructure formed in different stages of softening under annealing after moderate cold deformation on martensitic transformations and functional properties of alloy Ti – 50.2 at.% Ni used for actuators is studied. The work consists of two ports. The first part presents the results of diffraction and calorimetric studies reflecting the influence of a long hold (10 h) at the temperature of effective aging (430°C) on the characteristic temperatures of martensitic transformations. The second part is devoted to the influence of structural evolution and martensitic transformations on the characteristics of shape recovery. The conditions of implementation of anomalously high characteristics of shape recovery induced by nonisothermal loading are determined and analyzed.
