摘要：
A novel metastable beta Ti-25Nb-2Mo-4Sn (wt pct) alloy with high strength (1113 MPa) and low Young's modulus (65 GPa) was prepared. Nanometer-scaled alpha precipitates as well as the dislocations play a key role in strengthening. The beta phase containing low content of beta-stabilizers is stabilized with the assistance of thermomechanical treatment, resulting in a relatively low elastic modulus. Therefore, the current alloy performs high strength-to-modulus ratio and could be a potential candidate for biomedical applications.
