A new mathematical model of thixotropic casting based on the two-phase approach for the semi-solid metal alloys is presented. The corresponding numerical algorithm has been implemented in original computer software using the finite element method in the 3-D geometry and using the Lagrangian approach to flow description. The model has been verified by means of an original experiment of thixoforming in a model die specially designed for this purpose. Some particular cases of such casting and influence of operating parameters on the segregation phenomenon have been discussed.
