Controlled mechanical loading was applied to Ti-15Mo alloy during annealing at 550 ^∘C. Massive formation of the ω_\textrmiso phase from the parent β-phase occurred during annealing at 550 ^∘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→α 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.
