Abstract:Research and development of semisolid metal slurry processing technology was outlined; and a few representative SSM (semisolid metal processing) methods and the corresponding slurry processing technologies were presented; moreover, the formation mechanism of non-dendritic microstructure under coerced convection condition was summarized. The rheoforming route, whose process flow was simple and prime cost was low, has become the development direction at present. The necessary condition of manufacturing high-quality semisolid processed parts is that the supplied semisolid slurry has high density of nuclei suspending uniformly in the bulk melt.
