New Type of Ultra-Fine Grained Microstructure in Ti-6Al-4V Alloy for Enhancing Superplasticity

Abstract:

This work presents a formation of ultrafine-grained microstructure (d ~ 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.α
