Abstract: A casting method includes forming a seed. The seed has a first end and a second end. The forming includes bending a seed precursor. The seed second end is placed in contact or spaced facing relation a chill plate. The first end is contacted with molten material. The molten material is cooled and solidifies so that a crystalline structure of the seed propagates into the solidifying material. 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.

Abstract: A solution is provided and includes a strong base, a corrosion inhibitor, wherein the strong base is an alkali metal hydroxide, wherein the corrosion inhibitor is at least one of an organic acid having a-COOH functional group or an alkali metal salt of one of an organic acid having a-COOH functional group.

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

Abstract: A casting method includes passing a metallic spacer through respective apertures in at least two ceramic cores to an installed condition wherein the spacer defines a minimum local separation between the at least two cores. The spacer has a shank and at least one arm extending from the shank. A sacrificial pattern material is molded over the metallic spacer and the at least two ceramic cores and then shelled and fired. An alloy is cast in the shell the shell is removed from the cast alloy.

Abstract: A casting method includes: forming a seed, the seed having a first end and a second end, the forming including bending a seed precursor; placing the seed second end in contact or spaced facing relation with a chill plate; contacting the first end with molten material; 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 of the seed proximate the first end relative to a thickness of the seed proximate the second end.

Abstract: A cast part includes an outermost wall, at least one inner wall defining at least two internal passages and at least one cast cooling fin extending from an outer surface. The cast part including a cross-sectional circular area spanning at least a portion of each of four internal passages includes a ratio of interior empty space to inner wall space that improves heat transfer.

Abstract: A cast part includes an outermost wall, at least one inner wall defining at least two internal passages and at least one cast cooling fin extending from an outer surface. The cooling fin includes a ratio of fin height to an average fin thickness that is greater than 2.0 and no more than 18.0. A method is also disclosed.
