Abstract: A method for manufacturing a gas turbine engine component from a molybdenum-rich alloy. The method includes the steps of providing a molybdenum powder of at least 50% molybdenum by weight, extruding the molybdenum powder to provide a first shape, forming the first shape to a second shape and forging the second shape to provide a third shape.

Abstract: An embodiment of an apparatus includes a centrifugal drive unit, an arm assembly, an optional dynamic balancing ring, and a workpiece fixture. The arm assembly is operatively connected to the centrifugal drive unit and configured to revolve about a primary axis perpendicular to the arm. The workpiece fixture is mounted to the arm assembly, and is configured to rotate at least one workpiece about at least one secondary axis outboard of the primary axis.

Abstract: An exemplary method for determining a set of additive manufacturing parameters includes, a) determining a nominal parameter of at least one surface of a component, b) determining at least a second order variation in the nominal parameter, c) predicting an actual resultant dimension based at least in part on the nominal parameter and the second order variation, and d) adjusting at least one additive manufacturing process parameter in response to the predicted actual resultant dimension.

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 method for finishing a film cooled article includes providing a film cooled article including at least one inner cooling plenum and at least one opening connecting the inner cooling plenum to an exterior surface of the film cooled article, positioning a machining element in contact with the exterior surface of the film cooled article, automatically moving the machining element along the exterior surface while maintaining contact between the machining tool and the surface, identifying an actual position of at least one film opening based on sensory feedback from the machining element using a controller, removing material from the exterior surface at the at least one film opening using the machining element, thereby creating a depression at the at least one film opening.
