Abstract

Submicron-sized β grains were attained in a metastable βTi 77.5V15.9Al3.6Sn3.0 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.
