Phase-field simulation of equiaxed structure formation with growth, motion and collision of multiple dendrites

Abstract

In solidification of metal and alloy, an equiaxed structure is formed through the growth, motion and collision of multiple dendrites. In this study, we construct a model expressing the formation process of equiaxed structure by coupling multi-phase-field equation, lattice Boltzmann equation and equation of motion. Furthermore, we challenge to simulate the formation process of equiaxed structure.
