Abstract

The microstructural change of β titanium alloys, Ti-15V-3Cr-3Sn-3Al and Ti-10V-2Fe-3Al, and an (α + β) titanium alloy, Ti-6Al-4V during hot deformation at temperatures in β single-phase and (α + β) two-phase regions was studied. For the β titanium alloys, dynamic recovery takes place dominantly within β grains during deformation in the β single-phase region although some discontinuous dynamic recrystallization occurs along β grain boundaries. The size and fraction of recrystallized β grains increase as strain rate decreases or the deformation temperature rises.
