摘要： A casting method includes forming a seed (20, 800). The seed has a first end (24) and a second end (22) and an inner diameter (ID) surface (34) and an outer diameter (OD) surface (36). The seed second end (22) is placed in contact or spaced facing relation with a chill plate (102). The first end (24) is contacted with molten material (50). The molten material is cooled and solidified so that a crystalline structure of the seed (20) propagates into the solidifying material (50). At least a portion of the seed (20) contacted with the molten material (50) has a solidus higher than a solidus of at least an initial pour portion (910) of the molten material (50).

摘要： A cast part (12) includes an outermost wall (65), at least one inner wall (40a, 40b, 40c) defining at least two internal passages (28) and at least one cast cooling fin (24) extending from an outer surface (90A, 90B). The cooling fin (24) includes a ratio of fin height (104) to an average fin thickness (92) that is greater than 2.0 and no more than 18.0. A method is also disclosed.
