Abstract

An apparatus and a method for forming a semi-solid thixotropic slurry. The apparatus includes a duplex mold arrangement for postponing solidification within the mold until the molten metal is within a magnetic field for providing magnetohydrodynamic stirring. The duplex mold includes a first portion of low thermal conductivity and a second portion of high conductivity.
