摘要： A casting method includes: forming a seed (20), the seed having a first end (24) and a second end (22), the forming including bending a seed precursor; placing the seed second end in contact or spaced facing relation with a chill plate (102); contacting the first end with molten material (50); and cooling and solidifying the molten material so that a crystalline structure of the seed propagates into the solidifying material. The forming further included reducing a thickness (T U ) of the seed proximate the first end relative to a thickness (T 1 ) of the seed proximate the second end.

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.

摘要： A process includes: a first casting modelling stage (22) producing resulting casting parameters; a second casting modelling stage (24) performed using the resulting casting parameters of the first casting modelling stage (22) and of higher fidelity than the first casting modelling stage (22); in parallel with the second casting modelling stage (24), a casting trial (26) using the resulting casting parameters of the first casting modelling stage (22); and evaluating the casting trial (26).

摘要： 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 (252, 292, 302) leaving the bent seed precursor (254, 297, 304) protruding from a first end of the sleeve.
