Abstract Scope |
Granular or dendritic fragmentation that occurs in semi-solid deformation has great potential to refine the solidification microstructure. However, the detailed fragmentation mechanism in such a semi-solid state is yet to be fully understood due to the complexity of the phenomenon. To elucidate the mechanism, the numerical simulation is essential. In this study, we developed a multi-physics model and its simulation method that reproduces fragmentation in the semi-solid state. In the model, solid morphological change and grain boundary formation are represented by phase-field method, liquid flow is represented by lattice Boltzmann method, and solid deformation and motion are represented by material point method. Through some simulations, we investigated the ability of the method for expressing the fragmentation. |
