A novel approach to achieve an extraordinary high stress recovery shape memory effect based on thermal cycling of stressinduced martensite is proposed. An alternative thermodynamic path is considered in order to achieve outstanding functional properties of Ni-rich NiTi alloys, which are commonly used at room or body temperature as superelastic materials.

Abstract

A novel approach to achieve an extraordinary high stress recovery shape memory effect based on thermal cycling of stressinduced martensite is proposed. An alternative thermodynamic path is considered in order to achieve outstanding functional properties of Ni-rich NiTi alloys, which are commonly used at room or body temperature as superelastic materials. Fatigue tests revealed excellent stability of the material subjected to the novel thermomechanical path, confirming its suitability for employment in highperformance shape memory actuators.
