• The effect of Sn content on the phase constitution and mechanical properties of Ti-6Cr-Sn (mol%) alloy ωas investigated. Both Ti-6Cr-5Sn and Ti-6Cr3Sn alloys were β single phase at room temperature. Though increase in the Sn content to 5% was effective in increasing the ultimate tensile strength and yield stress, it sharply decreased the fracture strain and eliminated the superelastic recovery strain. The diffraction peaks of α″ martensite phase appeared in the XRD profile of Ti-6Cr-3Sn alloy after the tensile deformation, while not in the Ti-6Cr-5Sn alloy. These results indicate that the Sn addition decreases martensitic transformation temperature.
