Fatigue failure in NiTi based shape memory alloys (SMAs) that are in the austenitic state is accelerated by the progressive accumulation of stress-induced martensite (SIM) under cyclic loading, even when the maximum stress of the fatigue cycle is well below that required for stress-induced martensit...
