The authors investigated the effects of Sn additions on the microstructure, physical and mechanical properties of Ti-24Nb-4Zr-(0.75-0.81) Sn (wt.%) alloys. The result reveals that the stability of the alloys was improved by Sn addition, which had close correlation with the compositional specific electrons per atom ratios (e/a), and the room temperature mechanical behaviors could not show a trend with Sn constituents in all the alloys, before the anneal treatment. The high strength and toughness exhibited by Ti-24Nb-4Zr-8Sn and Ti-24Nb-4Zr-8.1Sn alloys means that they can be useful for Engineering applications, where strength to weight ratio is essential.
Keywords: Titanium alloy; mechanical strength; physical properties; electrons per atom ratios (e/a); phase stability.
