Abstract: A method for abrasive flow machining includes moving an abrasive media through a high-aspect passage of a workpiece. Local pressure of the abrasive media is increased at target abrasion surfaces of the high-aspect passage using a passage geometry that is configured to direct flow of the abrasive media into the target abrasion surfaces such that the target abrasion surfaces are preferentially polished by the abrasive media over other, non-targeted surfaces of the high-aspect passage at which the flow of the abrasive media is not directed into.

Abstract: A multi-component fastener is provided having a body and a sleeve. The body has a shank that extends lengthwise between a head and a distal end. The shank includes a first outer surface. The body includes a first material. The sleeve has a wall defined by an outer surface and an inner surface. The inner surface defines an interior cavity. The wall extends lengthwise between a first end and a second end. At least a portion of the sleeve outer surface contiguous with the first end is threaded. The sleeve includes a second material that is dissimilar to the first material. A portion of the shank including the distal end is disposed within the interior cavity of the sleeve. The sleeve and the shank are fixed to one another.

Abstract: A method of making a part including a solid portion with an internal passage includes building the part using an additive manufacturing process that builds the part on a layer-by-layer basis. The solid portion of the part is formed. A solid core is formed within at least a portion of the internal passage. Forming the solid core includes forming an attachment feature and forming a shearing feature. Material that is not fused, either semi-sintered or un-sintered, is positioned between the solid portion and the solid core. A force selected from the group consisting of a tensile, compressive, vibratory, and torsional force is applied to the solid core at the attachment feature. The material is then shorn with the shearing feature.
