Abstract. The structure, mechanical and functional properties of the aging Ti-50.8 at.% Ni shape memory alloy after deformation by compression in a wide temperature range of
100–900 °С and post-deformation annealing at 430 °С was studied. The temperature regions of dynamic softening processes (recovery, polygonization and recrystallization) were determined as a result of comparative study (TEM, X-ray, changes in properties). It was found that dispersion hardening due to precipitation of Ti3Ni4 phase particles is accompanied by an increase in functional properties.
