New thermomechanically treated NiTi alloys - a review.
TL;DR: Thermomechanically treated NiTi alloys have been reported to be more flexible with improved cyclic fatigue resistance and greater angle of deflection at failure when compared to conventional NiTi, and may be attributed to a modified phase composition containing varying amounts of R-phase and martensite.
