| contents | Controlled mechanical loading was applied to Ti-15Mo alloy during annealing at 550 $^\circ$C. Massive formation of the $ω_{\textrm{iso}}$ phase from the parent $β$-phase occurred during annealing at 550 $^\circ$C without external stress or with stress well below the yield stress. Moreover, a massive $α$ phase precipitation takes place under simultaneous annealing and plastic deformation. Plastic deformation plays a key role in $β\rightarrowα$ transformation and achieving refined $α+β$ type microstructure resulted in improved mechanical properties. Studying phase transformations during plastic deformation is critical for understanding and optimizing thermomechanical processing of metastable $β$-Ti alloys. |
