Abstract

Easy deformation-induced nanostructuring was found in a Ti-Nb-Ta-In β alloy with low stability against α″ martensitic transformation. Upon severe plastic deformation at the sample center, the reversible β→α″ martensitic transformation plays a significant role for grain refinement. A possible mechanism is proposed, in which the formation of fine martensite, the interaction among slip dislocations, martensite and twins, and the reversible transition from α″ back to β phase are considered as the main causes leading to pronounced grain refinement to the nanoscale.
