Semi-solid metal (SSM) processing is relatively a new metal processing technique. Semi-solid processing is characterized by processing of a suitable alloy with non-dendritic microstructure, in the solid-liquid temperature range. A lot of research work in recent years has made this process industrially viable for production of different products mainly for automotive industry. Different processes and processing techniques have been developed and marketed successfully. Semi-solid processes although require higher initial capital cost but can produce parts with high mechanical properties and soundness with lower weight compared to conventional processes. Currently research is more focused to understand the formation of globular microstructure and simulate the semi-solid processes for better control.
