摘要： An extension is formed directly on the end of an article by dipping the end into a molten bath of an alloy, followed by withdrawal of the end at a rate sufficient to form the extension. Extensions formed have a microstructure that is continuous and compatible with that of the article. Such microstructures may include epitaxial growth of the extension onto the microstructure of the article. The method establishes a temperature gradient within the article that may be controlled by heating and/or cooling the article during the practice of the method.

摘要： An extension is formed directly on an article by dipping a portion or end of the article having an attached integral mandrel into a molten bath 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 is utilized over the dipped end of the article and the integral mandrel with a mold cavity that generally defines the shape of the extension to be formed. The mold may be formed in situ on the mandrel, or preformed and attached to the subject article over the mandrel. The integral mandrel is melted within the mold by dipping the mandrel into the molten alloy. The mandrel acts as a buffer between the molten material and the article while permitting melting of the article end and solidification of the integral extension. Extensions formed by the method of this invention have a microstructure that is continuous and compatible with that of the article. Such microstructures may include epitaxial growth of the extension from the microstructure 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 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 is formed directly on an article by dipping a portion or end of the article into a molten bath 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 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 that is continuous and compatible with that of the article. Such microstructures may include epitaxial growth of the extension from the microstructure 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 filament comprises a generally thin metal component, such as a sheet, ribbon, or foil. The filament comprises at least one emitter, at least one current-condensing structure and a tab on each end of the at least one emitter. Each tab is connectable to a support system, comprising for example a lead and attachment post. When a current is passed through the filament, the current-condensing structure establishes current flow through the filament resulting in a desired temperature distribution across the emitter, for example a substantially uniform temperature distribution. A predictive tool for determining a geometry of a filament to provide a desired temperature distribution is set forth. The filament may be curved, and methods and systems for providing a curved filament are also provided. Attachment systems are further disclosed for attaching an emitter to a support structure.

摘要： A furnace component having a tungsten-based substrate whose surface is protected by a rhenium-based layer in order to render the component less reactive to quartz, glass and other forms of silica. The layer preferably consists essentially of rhenium or rhenium with alloying additions of tungsten. The substrate may be formed of concentric layers of different tungsten-based alloys in order to tailor the physical and mechanical properties of the component. A preferred method of forming the rhenium layer is to wrap the substrate with a rhenium-based wire, and then heat the wire and substrate to sinter and bond the wire to the substrate. Alternatively, the substrate and rhenium layer can be formed by isostatic pressing. Both methods are performed so that the substrate and layer have densities of at least about 96% of their respective theoretical densities.

摘要： A method for directional solidification (DS) of a molten material, and an apparatus therefor. The method generally entails the use of a container having a base and peripheral wall that define an interior of the container, an induction coil for heating the contents of the container and generating an electromagnetic field, and means for controllably separating the container from the heating means and the electromagnetic field, such as by withdrawing the container from the heating means and electromagnetic field. Using such an apparatus, a material is heated within the container to yield a melt that is substantially prevented from contacting the wall of the container as a result of being at least partially levitated by the electromagnetic field. The container is then separated, e.g., withdrawn from the heating means and the electromagnetic field so as to cause directional solidification of the melt while the majority of the melt remains spaced apart from the wall of the container, yielding a directionally solidified article whose composition has not been significantly affected by reactions with the container. The invention is particularly directed to the production of DS ingots of high temperature materials containing one or more reactive elements.
