Semi-solidified metal compositions are stably produced by pouring molten metal into a cooling agitation vessel, agitating it while cooling to produce a slurry of semi-solidified metal composition at a solid-liquid coexistent state and discharging out the semi-solidified metal composition from a discharge port of the vessel. In this case, the cooling agitation is carried out so that a relation of fraction solid, solidification rate and shear rate satisfies the following equation (1)

Process for the production of semi-solidified metal composition

In a process and an apparatus for stably and continuously producing a solid-liquid metal mixture in which non-dendritic primary solid particles are dispersed into the remaining liquid matrix, molten metal is charged into a clearance between a wall member and a rotating agitator composed of a cylindrical drum having a horizontally rotational axis.
