Abstract

We have presented a formation of ultrafine-grained microstructure (d α ≈ 0.2 μm) of industrial Ti-6Al-4V alloy produced by the hot compression of a sample with the acicular α′ martensite starting microstructure. The hot-deformation behavior was different from the case of the conventional (α + β) starting microstructure, that is, the phase transformation of α′/(α + β) during hot working enhanced the microstructural conversion, especially under the conditions of a low temperature and a high-strain rate.
