The Challenge and Progress in Macro- and Micro-modeling and Simulation of Squeeze Casting Process

Abstract

Squeeze casting is an advanced manufacturing process for aluminum and magnesium alloys, which produces high integrity and heat-treatable cast components. The physics involved in squeeze casting is pressurized solidification and it is important to understand the fundamental knowledge of pressurized solidification and to develop numerical models both at macro- and micro-scales. This review presents the major challenge and novel research dedicated to macro- and micro-modeling on squeeze casting of aluminum and magnesium alloys, including metal displacement and free surface tracking, thermal–mechanical coupled simulation, casting–mold interfacial heat transfer model, shrinkage defect and macrosegregation prediction, pressurized solidification and microstructure modeling, through-process modeling, etc. Finally, the prospects of the macro- and micro-modeling on squeeze casting process are presented.
