The deformation rate is the critical parameter for the phase transforming mechanism and subsequently the morphology of Ti‐Al‐V alloys, which in turn determines the feasibility of high‐speed deformation. The evolution of defect‐free equiaxed microstructures is due to dislocation‐induced heterogeneous nucleation and growth. The Figure shows a microstructure of a Ti‐6Al‐4V specimen deformed at 1000 °C in a backscattered SEM image.
