The shape memory effect is closely related to a martensitic phase transformation and the memory strain (the recoverable strain) is brought about by stress induced martensitic phase transformation or by reorientation of the martensite variants during stressing. Finally, the most favorably oriented martensite B19{prime} with respect to the stress transforms back to the high temperature phase B2. There is a lot of information concerning deformation behavior of annealed TiNi polycrystalline alloys as well as single crystals. This paper concentrates on the influence of work hardening and annealing on substructure characteristics and deformation behavior of TiNi alloys.
