Effect of scanning strategy on variant selection in additively manufactured Ti-6Al-4V

Additive manufacturing of the Ti-6Al-4 V alloy is increasingly popular for making complex shaped parts. This alloy undergoes a transformation from the body-centred cubic β phase to the hexagonally close-packed α phase following solidification. There are currently gaps in the understanding of relationships between the processing conditions and the final material microstructure. In particular, the role of α variant selection mechanisms within...
