| Abstract: | Existing models for solute redistribution (microsegregation) during solidificaiton are reviewed. Some typical models are applied for numerical simulation of heat and mass transfer with phase change under experimental condition in a crystallizor of inverse casting. The study shows that the effects of microsegregation models on the formation of the new phase cannot be neglected. |
