摘要： A method is disclosed for removing casting defects (5) from an article (1) with an oriented microstructure. The method comprises the steps of locating at least one casting defect (5) and melting the casting defect (5) locally by a heat source (7) to a depth at least as great as the casting defect (5) itself. Subsequently the molten material is solidified epitaxially with respect to the surrounding oriented microstructure of the article (1) in a way that the resulting solidified area is substantially free of any defect.

摘要： A refractory lining is formed in a furnace (40) by providing a carrier (20) for a lining form (10) which has dimensions that provide a uniform space for the introduction of refractory material (50) when the lining form (10) is concentrically located within the furnace (40). The carrier (20) concentrically engages and is attached to the lining form (10), and includes a portion that engages the furnace (40) and locates the carrier (20) and the lining form (10), when attached, concentrically within the furnace (40) to provide a uniform space therebetween. The carrier (20) can also have an upper surface that slopes downwardly from adjacent its center to its periphery to convey particulate refractory material (50) poured onto the surface into the space between the lining form (10) and the furnace (40). Further, a fixture is provided to hold the lining form (10) concentric while the particulate refractory material (50) is compacted by vibration.

摘要： A method for providing an integral extension on an article comprises selecting an article (100) comprising an extension end, an extension bonding surface and an outer surface defined by the cross sectional shape. The extension end also has a superalloy composition and a directionally oriented crystal structure. A mandrel (200) is attached to the extension bonding surface. The mandrel has a cross sectional shape that is compatible with the cross sectional shape of the extension end and an outer surface that communicates with the outer surface of the extension end. The mandrel also has an alloy composition that is compatible with the superalloy composition. A ceramic mould (300) is formed over the outer surface of the mandrel and a portion of the outer surface of the extension end. The mould has a cavity with a shape that is defined by the mandrel and defines the shape of the integral extension. The mandrel is melted under controlled conditions by application of an external heating means, the article, mandrel and mould being oriented either prior to or during the melting so that the molten mandrel contacts the extension bonding surface, for a time sufficient to permit the extension bonding surface to be heated by and interact with the molten mandrel as a microstructure growth seed. The extension end (700) is cooled under controlled thermal conditions so as to cause the molten mandrel to solidify on the growth seed, at an interface between them that moves from the extension bonding surface into the molten mandrel, as an integral extension that conforms to the shape of the mould cavity and has a microstructure that is compatible with the microstructure of the extension end. The controlled thermal conditions comprise maintaining a temperature gradient within the article such that the temperature is highest at the interface and decreases within the article as a function of increasing distance from the interface. Also claimed is a second method for providing an integral extension on an article.

摘要： In one aspect, a method (200, 400) for performing in situ repairs of internal components of a gas turbine engine (10) may generally include inserting a repair tool (102, 302) through an access port (62) of the gas turbine engine (10) such that the repair tool (102, 302) includes a tip end (112, 312) positioned within the gas turbine engine (10) and a material supply end (114, 314) positioned outside the gas turbine engine (10). The method may also include positioning the tip end (112, 312) of the repair tool (102, 302) adjacent to a defect (106) of an internal component (104) of the gas turbine engine (10), wherein the defect (106) defines a fillable volume (108) along a portion of the internal component (104). In addition, the method (200, 400) may include supplying a filler material to the tip end (112, 312) of the repair tool (102, 302) and expelling the filler material from the tip end (112, 312) of the repair tool (102, 302) such that the fillable volume (108) is at least partially filled with the filler material. The filler material may be liquid metal or solid powder material. A corresponding system for performing in situ repair of internal components of a gas turbine engine is also provided.
