%X Different heat treatments, including quenching and hot isostatic pressing, were conducted on the Ti–24Nb–4Zr–8Sn alloy fabricated by powder metallurgy, in order to improve its mechanical properties. As-sintered samples have high oxygen content over 3000 ppm, resulting in α phase precipitates and low ductility. But the mechanical properties can be improved by solution treatment at a suitable temperature and subsequent quenching. Although the treatment is only effective within a narrow temperature window ranging from 950 to 1000 °C, the treatment can completely eliminate the detrimental α phase and substantially improve the ductility of the alloy from 2% to 19.33%. In comparison, although the hot isostatic pressing can improve the density of the as-sintered alloy to nearly fully dense, it proves unable to remove the α phase from the material or improve its ductility alone.
