Dendrite fragmentation is one of the most remarkable phenomena in solidification of alloys, because it would be potential nuclei of equiaxed structure. However, the mechanism of dendrite fragmentation is not clarified yet. In this study, a numerical model, which can simulate the dendrite fragmentation and following flow of a fragmented part, is developed by coupling phase-field method, lattice Boltzmann method and equations of motion. This model will be an effective prediction scheme of the dendrite fragmentation.
