Globularization using heat treatment in additively manufactured Ti-6Al-4V for high strength and toughness

Acta Materialia, 2019
A bimodal globularized microstructure in contrast to martensitic laths is known to impart high strength and toughness in Ti-6Al-4V. Heat treatment for the phase transformation of the laths to the globularized microstructure must be preceded by plastic ...
