Abstract
In this study, the mechanical properties of Ti–13Nb–7Sn–4Mo (wt%) was improved through 90% cold rolling and subsequent aging treatment under different aging temperatures (500, 550, and 600°C) and times (30, 60, and 120 min). After aging treatment, the alloy showed a β + α″ + α structure, in which the α″ phase contributed to its low elastic modulus (58.5–73.4 GPa) and the nano α precipitates contributed to its high bending strength (> 1230 MPa). The alloy exhibited the highest bending-strength/elastic-modulus ratio (×1000) (23.3) after 90% cold rolling and aging at 600°C for 30 min.
