Research and Development on semisolid metal processing technology was summarized in this paper; and a few representative SSM methods and the correspondingly slurry processing technologies were presented

moreover

the formation mechanism of non-dendritic microstructure under coerced convection. The rheoforming route

in which process flow was simple and the prime cost was low

has been the development direction

and the necessarily condition aimed to manufacture high quality semisolid processed parts is that the supplied semisolid slurry has high density of nuclei suspending uniformly in the bulk melt.
