  • Process for the production of semi-solidified metal composition
    Patent number: 5555926
    Abstract: A semi-solidified metal composition having an excellent workability is continuously produced by pouring molten metal into an upper part of a cooling agitation mold, agitating it while cooling to produce a slurry of solid-liquid mixed phase containing non-dendritic primary solid particles dispersed therein and discharging out the slurry from a lower part of the cooling agitation mold. In this case, a ratio of shear strain rate at a solid-liquid interface to solidification rate of molten metal is adjusted to a value exceeding 8000 in the cooling agitation mold.
