Effect of the structural and phase state on the deformation behavior and mechanical properties of the ultrafine-grained titanium alloy (Ti–Al–V–Мо) at temperatures in the range of 293–973 K

Аннотация

The development of plastic deformation in an ultrafine-grained titanium alloy (Ti–Al–V–Mo; hereinafter VT16 alloy) under tension with a rate of 6.9·10⁻³ s⁻¹ in the temperature range of 293–973 K is investigated depending on the structure and phase composition of the alloy. It has been established that the deviation of the phase composition from the equilibrium one toward the increasing β phase enhances the resistance of the UFG VT16 alloy to the localization of plastic deformation during tension at low temperatures (293–673 K). Under tension of the UFG VT16 alloy in the temperature range of the superplastic flow (823–973 K), the indicated deviation of the phase composition from the equilibrium one contributes to a greater elongation to failure.
