Abstract

This work presents a formation of ultrafine-grained microstructure (dα ~ 0.2 μm) with high fraction of high-angle boundary in industrial Ti-6Al-4V alloy produced by the hot compression of a sample with the acicular α′martensite starting microstructure. It is found that heterogeneous nucleation becomes dominant in the case of the α' starting microstructure.
