Abstract
A method of shaping a semisolid metal to provide shaped parts which are produced in a convenient, easy and inexpensive manner, without relying upon the conventional mechanical or electromagnetic agitation. The method includes feeding, without using a cooling jig, into an insulating vessel, a molten alloy containing an element for promoting generation of crystal nuclei and being held to be superheated to less than 100° C. above a liquidus temperature of the alloy; maintaining the molten alloy in the insulating vessel for 5 seconds to 60 minutes as the alloy is cooled at a cooling rate of 0.01° C./s to 3.0° C./s thereby crystallizing fine primary spherical crystals in an alloy solution containing a specified liquid fraction; and feeding the alloy solution into a forming mold for shaping the alloy under pressure.
