Abstract
The influence of thermomechanical conditions of induction of the shape memory effects (SME) by bending strain in the Ti-Ni shape memory alloy on the realization of SME and reversible SME (RSME) is studied. The values of reversible SME (ɛ r ) and RSME (ɛ TW ) deformations depend on the initial structural condition of the alloy, initial phase state upon thermomechanical aging, and time of holding in a hardened state. The obtained values of reversible deformation ɛ r (14.5%) and ɛ TW (5–6%) significantly exceed their conventionally attainable level. The results of investigation allow extension of the possibilities to control the complex of functional properties of the Ti-Ni alloy with shape memory.
