Stability of the martensite transformation dilatation during thermal cycling of Ti-49.8at.%Ni samples rolled at different temperatures was investigated. It was revealed that the dilatation jump is stable in the fragmented structure alloy subjected to rolling at low temperatures (470,570 K). In the case of high temperature rolling (670,770,870 K), when structure relaxation takes place as a result of recrystallization, the dilatation jump grows and saturates after about 25 thermal cycles. Such unstable dilatation is due to phase hardening of the relatively coarse grain material and increasing intensity of textured internal stress field. The latter is the reason of crystallographic texture inheritance.
