Predicting solid–liquid interfacial characteristics during rapid solidification

A numerical model capable of predicting cellular and dendritic growth at low and high velocities based on Hunt’s approach (Hunt, 1990) is proposed to quantify the degree of non-equilibrium at the solid–liquid interface and thus to determine if an additive manufacturing process route exhibits rapid solidification. The developed model accounts for various undercoolings, as well as the variation in the partition coefficient, liquidus slope, and …
