Abstract: Methods are described for attaching ceramic fibrous bodies to metallic substrates. Metal fibers or metal wires (18) are woven into the ceramic fibrous body (14) which is to be adjacent the substrate and the exposed portion of these fibers or wires is attached by brazing to the substrate.

Abstract: Weldable Cast Nickel Base Superalloy Nickel base superalloys of the type referred to as Waspaloy are rendered weldable by limiting the iron content to about one twentieth of that which is commonly present, adding small amounts of manganese to the alloy and removing the zirconium which is commonly present. In addition, the sulfur, bismuth and lead levels are held to the lowest possible limits, and preferably the aluminum and molybdenum are maintained in the lower half of their normal range. By implementing these alloying strategies, the weldability of the cast material is dramatically improved and for the first time castings of the Waspaloy materials are rendered consistently weldable on a commercial scale.

Abstract: A fushion welded surfacing process for use with crack prone substrates is described. The process involves the application of an intermediate layer of crack resistant alloy by fusion welding followed by the application of the desired final surfacing alloy by fusion welding. The intermediate layer is an age hardenable nickel superalloy to which intentional additions of manganese have been made. The final surfacing alloy may be of the hardfacing type or may be of a type which imparts corrosion and oxidation resistance to the underlying article.

Abstract: A die casting machine (18) includes a melting unit (24), a horizontal shot sleeve (30) in fluid communication with die cavity (36) for receiving molten titanium from the melting unit (24), and a plunger (40) sealing and moveable engagement with the shot sleeve (30) for forcing molten material from the shot sleeve (30) into the die cavity (36). The melting unit (24), the shot sleeve (30) and the die cavity (36) are maintained in a non-reactive environment. The material is melted to a low superheat, e.g. less than about 200 DEG F/95 DEG C. Molten material is then transferred from the melting unit (24) to the shot sleeve (30) to fill not more than about one half of the shot sleeve volume. The molten material is injected from the sleeve (30) into the die cavity (36) using the plunger (40) for solidification in the die cavity (36). The resulting articles have a fine average grain microstructure and are characterized by an absence of flowlines.

Abstract: A die cast article composed of titanium alloy is disclosed, and is preferably characterized by a transformed beta microstructure, a relatively fine average grain size and an absence of flow lines. Typical alloys include Ti 6Al-4V and Ti 6Al-2Sn-4Zr-2Mo. Exemplary articles include gas turbine engine components. The articles may be used in place of corresponding forged articles, and have at least comparable mechanical properties.
