In-situ observation of single variant α colony formation in Ti-6Al-4V

AE Davis, J Donoghue, JR Kennedy, N Byres… - Acta Materialia, 2021 - Elsevier
Much of the current understanding of the β→ α+ β phase transformation in the commercially
important titanium alloy Ti-6Al-4V (Ti64) is by inference from more β-stabilised analogues, or …

Insights into the selection mechanism of Widmanstätten growth by phase-field calculations

H Lebbad, B Appolaire, Y Le Bouar, A Finel - Acta Materialia, 2021 - Elsevier
We investigate the growth of Widmanstätten structures in metallic alloys with phase field
calculations. We show that elastic energy anisotropy associated with shear dominated …
