<p>A method of producing directionally solidified cast alloy articles is disclosed wherein a porous, shell mold having open-ended mold cavities is filled with molten alloy while seated on a low heat conductive surface and is allowed to cool. The filled mold is then moved to a highly heat conductive surface and is reheated to a temperature above the melting range of the alloy where a unidirectional temperature gradient is established along the length of the alloy within the mold to cause directional solidification of the alloy.</p> |
