Summary:The flow behaviour of semi-solid material is outlined and discussed. A representation of flow stress for AI-2024 in the semi-solid state and a numerical algorithm for updating the solid fraction during forging are proposed. Flow simulation by the finite element method in closed die forging to fabricate an automobile part has been performed and compared with experimental results. The information obtained from the simulation results are utilized in designing the preforms.
