Abstract Scope Metastable-β titanium alloys are of increasing interest for biomedical applications because of not only their great biocompatibility but also their potential shape memory or superelastic effects. Usually, shape memory effect is due to the reorientation of pre-existing α” martensite while superelasticity is due to reversible stress-induced martensitic (SIM) transformation from β phase to α” phase. In the present study, an abnormal shape memory effect is found from the non-reversible SIM transformation occurring from a full-β phase microstructure (annealed state) during tensile tests. An additional heat treatment at low temperature from the annealed state leads to a superelastic effect in the same alloy, pointing out the SIM transformation has become reversible. It will be shown by means of transmission electron microscopy (TEM) observations that the reversibility of SIM α” transformation can be tuned by a slight change in the nano-scale precipitation in initial β phase.
