Shape memory behaviour in NiTi alloys is very sensitive to the alloy chemical composition on one hand, and to the local stress state caused by dislocation structure and/or precipitates on the other. As the alloys find many applications, including applications in medicine as different types of implants, the possibility of controlling the transformation temperatures is very important from that point of view. In the work transformation sequences, temperatures and shape recovery structures caused by deformation and subsequent annealing as well as precipitation process produced by ageing on the above properties will be discussed.
