Abstract
The shape memory effect and superelasticity of Ti-3Zr-2Sn-3Mo-l5Nb (TLM) alloy under different conditions of deformations, temperatures, deformation strains and heat treatments were studied by bending and tensile tests. The results indicate that TLM alloy specimens hot rolled or cooled from α+β dual phase region have higher shape recovery ratio than that cooled from ft single phase region their the maximum completely recovery strain reaches 1.8%. The shape recovery ratio decreases with the increase of the total deformation strain which has been proved in many other beta titanium alloys. The TLM alloy specimen cooled from β single phase region in air exhibits the best superelasticity compared with that of hot rolled or aged specimens.
