Abstract: Investigations of the microstructure of stress-induced martensite (SIM) and its evolution in a Ti36Ni49Hf15 alloy were discussed. A discussion on the reasons for no stress plateau in tensile stress-strain curve of the Ti36Ni49Hf15 alloy deformed in an austenite state was also presented. Results showed that the morphology of SIM changed from preferentially orientated to variant-crashed/variant-intersected with increasing the deformation strain. It was also noticed that the poor shape memory effect (SME) was be due to the dislocation slip during the stress-induced martensitic transformation.
