In the present work, a Ti-based shape memory alloy with the composition of Ti–7.5Nb–4Mo–1Sn was designed based on the d-electron orbit theory. The shape memory and superelastic behavior of the alloy were investigated. It is found that the martensitic transformation temperature of the alloy is near 261 K. The tensile and the thermal cycling testing results show that the alloy exhibits the stable shape memory effect and superelasticity at room temperature. The maximum recovered strain of the alloy is 4.83%.
Research highlights► A Ti-based shape memory alloy, Ti–7.5Nb–4Mo–1Sn, was designed. ► The martensitic transformation start temperature of the alloy, Ms, is 261 K. ► The alloy exhibits good shape memory and superelastic behaviors. ► The alloy also shows a good superelastic stability at room temperature. ► The Ti–5Mo–7.5Nb–1Sn alloy has a potential application as a biomedical material.
