Abstract

The starter section 32 of a directional solidification mold 20 contains a seed 28. Molten metal is flowed over and about the seed 28 to heat and partially melt it. A selector section 34 of the mold has reduced cross section compared to the starter section so that only epitaxially solidified metal will be formed in the article section. A barrier layer 40, preferably of ceramic material, resistive to molton metal is preferably applied to portions of the seed to facilitate its removal and reuse. <IMAGE>
