Abstract

Submicron-sized β grains were attained in a metastable βTi _77.5V_15.9Al_3.6Sn_3.0 alloy through the strain-induced martensite and its reverse transformations process, characterized by a single cycle of conventional cold rolling and annealing. The grain refinement was attributed mainly to the reverse-transformed β grains from nanosized α′′ and α phases. During the continuous heating of the cold-rolled specimen, the β to α transformation occurred first, and α′′ to β and α to β reverse transformations took place sequentially.
