摘要： One embodiment is a method. The method includes providing a casting apparatus including a first chamber and a second chamber, wherein the first chamber is isolated from the second chamber. The method includes charging a superalloy composition into a crucible present in the first chamber and melting the superalloy composition in the crucible to form a molten superalloy composition. The method includes discharging the molten superalloy composition into a casting mold present in the second chamber; applying a positive pressure to the first chamber to create a first chamber pressure; and applying a vacuum to the second chamber to create a second chamber pressure, wherein the first chamber pressure is greater than the second chamber pressure. The method further includes casting at least one filament from the molten superalloy composition in the casting mold. An apparatus for casting a plurality of filaments is also provided.

摘要： A turbine component (10) formed from a niobium silicide-based composition is described. The component (10) can be compositionally-graded through at least a portion of its structure. A turbine blade (10) formed from a composition whi ch includes a niobium silicide alloy is also described. The blade includes an airfoil (12); an airfoil tip region (31); a platform (24) on which the airfoil (12) is mounted; and a dovetail root (26) attached to an underside of the platform (24). The niobiu m silicide alloy in at least one portion of the turbine blade (10) is compositionally different from the niobium silicide alloy in another portion of the blade. Processes for fabricating a niobium silicide-based turbine article are also described, using laser cladding techniques. Repair methods are also set forth in the application.

摘要： A method for forming integral extensions on the end of directionally oriented, superalloy articles, such as airfoil blading members or other components used in gas turbine or other turbine engines. An extension (20) is formed directly on an article (2) by dipping a portion or end (4) of the article into a molten bath (26) of a compatible alloy, followed by withdrawal of the end under controlled conditions sufficient to cause an integral extension to solidify on the article. A ceramic mold (16) is utilized over the dipped end of the article with a mold cavity that generally defines the shape of the extension to be formed. The mold may be formed in situ, or preformed and attached to the subject article. Extensions formed by the method of this invention have a microstructure (29) that is continuous and compatible with that of the article. Such microstructures may include epitaxial growth of the extension from the microstructure (10) of the article. The method establishes a temperature gradient within the article during solidification that may be further controlled by auxiliary heating and/or cooling of the article and/or extension during the practice of the method.

摘要： A method for providing an integral extension on an article, involves: (i) selecting an article comprising an extension end having a cross-sectional shape, an extension bonding surface and an outer surface defined by the cross-sectional shape, the extension end having a microstructure comprising a superalloy composition and a directionally oriented crystal structure; (ii) attaching a mandrel to the extension bonding surface, the mandrel having 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; (iii) forming a ceramic mould over the outer surface of the mandrel and the outer surface of the extension end, the mould having a mould cavity with a shape that is defined by the mandrel and that is adapted to define the shape of an integral extension, the mould having at least one gating means that communicates with the mould cavity; (iv) dipping the extension end of the article into a bath of a molten material having an alloy composition that is compatible with the superalloy so that the molten material enters the mould through the gating means and contacts the mandrel; (v) holding the mandrel in contact with the molten material for a time sufficient to allow the mandrel to be melted back to the bonding surface, the melted mandrel intermixing with and becoming part of the molten material, the holding time also being sufficient to allow the extension bonding surface to be heated by and interact with the molten material as a microstructure growth seed; and (vi) withdrawing the extension end from the molten material under controlled thermal conditions and at a rate which causes the molten material to solidify on the growth seed at an interface between them 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 method as described above where in step (iii) a preformed ceramic mould is attached to the bonding surface instead of being formed on it.
