摘要	Generally, deformation in Ti and Ti alloys are dominated by dislocations and deformation twins. In this work, a novel deformation band (DB) has been observed in the fully lamellar Ti-6Al-4V alloy. Through transmission electron microscopy (TEM) investigation, the DB is determined as a kink band (KB) resulting from the pile-up of < a > dislocations on {10(1) over bar 0} prismatic planes. More intriguingly, the KB can pass through the beta phase and then induce the phase transformation from beta to alpha phase, and the accompanying composition change may have been accommodated by diffusion driven by the high deformation energy under severe deformation conditions.
