With the deeply understanding of the development of semi-solid metals（SSM）processing

the conception of"Generalized SSM"and"SSM +"were proposed.So called"Generalized SSM"

indicating the melt on the liquidus temperature and the solid-liquid region via the high shearing of the melt and the forced uniform solidification to control nucleation and growth

is on the purpose of the structure refinement and the composition homogenization of the melt in nature

breaking the constraint of the composition of alloys.SSM +"

based on the generalized SSM technology

is considered as a means of transforming the traditional processing technology."Generalized SSM"can be combined with liquid forming processes such as vertical semi-continuous casting

horizontal continuous casting

high pressure casting

extrusion casting

vacuum casting

etc.

and it also can be combined with deformation process such as forging

extrusion

rolling and so on.
