In the present study, the effect of stress-induced martensite ageing on the two-way shape memory effect in aged at 773 K for 3 hours Ni5o.3Ti32.2Hf17.5polycrystals was investigated. It was found that stress-induced martensite aging in NiTiHf polycrystals results in generation of uniaxial tensile two-way shape memory effect of 2.3%. The mechanism of two-way shape memory effect was discussed and associated with both the martensite stabilization and the presence of internal elastic stress-fields.
