• Current Status and Perspectives on Wire and Arc Additive Manufacturing (WAAM) (2019, background): “This columnar structure is difficult to avoid since in low concentrations, aluminum and vanadium have a high solubility in titanium and do not partition ahead of the solidification front, becoming irrelevant as grain refiners [49].”
• Additive manufacturing of metallic components – Process, structure and properties (2018, background): “This is because of the high partition coefficients of Al and V in Ti which are close to one [405].”
• On the origin of microstructural banding in Ti-6Al4V wire-arc based high deposition rate additive manufacturing (2019, methodology): “This leads to minimal constitutional undercooling and a narrow mushy zone, which also prevents nucleation by dendrite fragmentation [28].”
• The effectiveness of combining rolling deformation with Wire–Arc Additive Manufacture on β-grain refinement and texture modification in Ti–6Al–4V (2016, unknown): “It has been previously noted that themain reason such a coarse grain structure develops is because the high thermal gradient in the melt pool and the alloy chemistry do not allow sufficient constitutional supercooling for nucleation to be possible ahead of the solidification front [17].”
