Abstract
The invention relates to an improved method of casting superalloy articles and more particularly to an apparatus for directionally solidifying eutectic superalloy compositions to produce a composite structure of a superalloy matrix reinforced with aligned carbide fibers. The improvement includes positioning a movable bed of a ceramic insulation around the mold such that as the mold is lowered the bed forms a continuous heat insulating barrier around the sides of the mold to prevent lateral heat transfer.
