Semisolid metal (SSM) processing is a special die casting process, where partially solidified metal slurry is injected into a die cavity to form die cast components. This article discusses the flow behavior of SSM slurry with emphasis on viscosity, rheological behavior, and yield strength. It illustrates microstructural formation of semisolids, under forced convection. The article concludes with an illustration that compares two SSM processes, namely, thixocasting and rheocasting.
