Abstract
A method of processing a casting is described. The method comprises removing a mold from a cast metal part without cold working surfaces of the cast metal part and thermally treating the cast metal part. The method can further comprise finishing the surfaces of the cast metal part after thermally treating such that any cold working of the surfaces of the cast metal part occurs after thermally treating such that no recast layer is formed in the cast metal part.
