This work examines the origin of the athermal α″ martensitic transformation in Ti-10V-2Fe-3Al alloys arising from high-speed hot deformation on the basis of chemical thermodynamics and the change in stored energy introduced by deformation. The value of the martensitic transformation starting temperature (M s) is strongly affected by various microstructural factors. This work reveals that a high accumulation of dislocation density, greater than 10 15 m -2, arising from high-speed deformation, resulted in an enhancement of athermal α″ martensitic transformations.
