The importance of processing of metal and metal matrix composites in semisolid state is increasing quite rapidly due to the distinct advantages it offers over similar methods of near-net-shape making. In this investigation we are using a two-phase model to predict the behavior of SSM in a three-dimensional isothermal flow through a sudden square expansion. The model is implemented computationally using a classical Galerkin-Finite element formulation with a segregated solution procedure. The model captures relative motion and particle crowding.
