The Interaction between Grains during Columnar-to-Equiaxed Transition in Laser Welding: A Phase-Field Study
A phase-field model was applied to study CET (columnar-to-equiaxed transition) during laser welding of an Al-Cu model alloy. A parametric study was performed to investigate the effects of nucleation undercooling for the equiaxed grains, nucleation density and location of the first nucleation seed ah...
