Orientation controlled pure Al and Al-Si alloys bicrystals of certain shape were prepared by Bridgman’s method using a “soft mold” technique. The crystal boundary behavior during crystal growth from melt was examined. It is determined by following two the factors:
(1) Extrinsic heat flow (heat flow in a specimen extrinsically depended on the temperature gradient in a furnace, the position of a specimen in a crucible, the shape and size of a specimen etc.)
(2) Intrinsic heat flow (heat flow in a specimen intrinsically depended on the formation of cellular structure and precipitates etc.).
