Abstract

A casting method includes forming a seed (20). The seed has a first end (24) and a second end (22). The forming includes bending a seed precursor. The seed second end (22) is placed in contact or spaced facing relation a chill plate (102). The first end is contacted with molten material (50). The molten material (50) is cooled and solidifies so that a crystalline structure of the seed (20) propagates into the solidifying material (50). The forming further includes inserting the bent seed precursor into a sleeve leaving the bent seed precursor protruding from a first end of the sleeve.
