Abstract
Disclosed is a method for directional solidification of large single crystal metal alloy castings using multiple seed crystals. Solidification interfaces emanate from the separate seeds, and merge to form a unitary solidification interface which is caused to move through the article. The crystallographic orientation of the seeds is controlled, to avoid unacceptable mismatch of crystal structure orientation where the separate interfaces merge.
