Dyanmic Young's modulus of beta-type Ti-Nb-(Sn) and Ti-Nb-O alloys quenched and aged after solution treatment was measured at room temperature as a function of alloy composition. Composition dependence of Young's modulus exhibited a minimum arising from athermal ω phase formation at lower alloying contents, and an increase in β phase stability at higher alloying contents. Young's modulus and hardness increased by isothermal ω formation on aging at 573K. Tin and oxygen additions to Ti-Nb decreased Young's modulus in quenched alloys.
