The apparatus and method for effecting the restructuring of metals disclosed herein provides a container for holding molten metal in a controlled atmospheric or vacuum environment into which an open-ended shell mold is immersed so that the wall of the mold separates and confines molten metal intended to be formed from the surrounding molten mass. A chill means is placed in engagement with the confined molten metal at the top opening of the mold which begins solidification thereof at the molten metal interface. Means are provided for moving the chill means so that the solidified portion of the formed part is withdrawn from the mold as required. Planned withdrawal of the solidified portion creates a continuously new interface area which then progressively solidifies until the formed part is completed.
