ABSTRACT:
A molding process utilizes a seed with a columnar grain structure for defining a desired grain structure in a completed casting. The seed is received within a seed cavity of a mold. The molten material adopts the orientation of the columns defined within the seed during solidification to form a completed molded article having a desired columnar grain structure.
