A near-β Ti-10V-3A1-3Fe (wt.%) alloy containing different a phase fractions after thermo- mechanical processing was compressed to 40% reduction. Detailed microstructure evaluation was carried out using high resolution scanning transmission electron microscopy and electron back-scattering diffraction. For the first time, deformation-induced β → α" and β → ω transformation products together with {332}{113}β and {112}{111}β twinning systems were simultaneously detected in a metastable β alloy containing an α phase. The effects of strain rate and β phase stability on the preferential activation of these reactions were analyzed. With an increase in β phase stability, stress-induced phase transformations were restricted and {112}{111}β twinning was dominant. Aleternatively, less stable β conditions or higher strain rates resulted in the dominance of the {332}{113}β twinning system.
