摘要： A casting system with auxiliary cooling onto a liquidus portion of the casting can produce a metal casting that comprises a fine-grain, homogeneous microstructure. The microstructure is essentially oxide- and sulfide-free, segregation defect free, and essentially free of voids caused by air entrapped during solidification of the metal from a liquidus state to a solid state. The casting system with auxiliary cooling onto a liquidus portion of the casting can comprises an electroslag refining system as a source of liquid metal; a nucleated casting system; and at least one cooling system that supplies coolant onto a liquidus portion of the casting. The liquidus portion of the casting is cooled in a manner sufficient to provide a casting microstructure that comprises a fine-grain, homogeneous microstructure that is essentially oxide- and sulfide-free, segregation defect free, and essentially free of voids caused by air entrapped during solidification from a liquidus state to a solid state.

摘要： A VAR process is conducted in an apparatus (10) characterized by a crucible wall that provides a stable shelf anchor. The VAR apparatus includes a furnace chamber (14), a consumable electrode (12) formed of a material to be remelted within the furnace chamber and a crucible (16) within the furnace chamber. The crucible (16) has a wall that forms a vessel to collect melt material from the consumable electrode (12). At least part of the wall is textured to provide area for mechanical stabilization of the shelf (42) as the underside of the shelf melts and the upper side of the shelf forms. In a vacuum arc remelting process, a consumable electrode (12) is loaded into a furnace chamber above a cooled crucible having a textured wall that forms a vessel to collect melt material from the consumable electrode (12). The process includes striking a direct electric current between the electrode and a bottom of the crucible (16) to cause melting of material from a tip of the electrode. Melt material is collected from the tip in the crucible (16). The melt material is cooled to form an ingot characterized by a shelf of solidified material forming adjacent the textured section of the crucible (16) wall in advance of a lower boundary of solidifying material.

摘要： Apparatus comprises a molten metal spray atomiser having: (a) an oval or elliptically shaped hollow manifold ring, forming an aperture for the passage through of a stream of molten metal; (b) gas supply to the manifold for pressure ejection from the manifold through a number of nozzles, to direct the gas jets onto the molten metal stream and form a molten metal droplet spray; and (c) mounting support structure allowing angular rotation of the atomiser about an axis radially across the aperture and manifold minor axis. Also claimed is an electroslag refining plant having a reservoir of molten metal feeding a molten metal stream to an atomiser, and using the claimed apparatus above, to form a spray pattern of metal droplets.

摘要： Methods for direct writing of single crystal super alloys and metals are provided. The method can include: heating a substrate (23) positioned on a base plate (22) to a predetermined temperature using a first heater (24); using a laser (26) to form a melt pool (34) on a surface of the substrate (23); introducing a superalloy powder (32) to the melt pool (34); measuring the temperature of the melt pool (34); receiving the temperature measured at a controller (40); and using an auxiliary heat source (41) in communication with the controller (40) to adjust the temperature of the melt pool (34). The predetermined temperature is below the substrate's melting point. The laser (26) and the base plate (22) are movable relative to each other, with the laser (26) being used for direct metal deposition. An apparatus (20) is also generally provided for direct writing of single crystal super alloys and metals.

摘要： A method for manufacturing a fuel contacting component that facilitates reducing coke formation on at least one surface of the fuel contacting component is disclosed herein. The method includes applying a slurry composition including a powder including aluminum to the component surface, wherein the fuel contacting component is formed by an additive manufacturing process. The slum' composition is heat treated to diffuse the aluminum into the component surface. The heat treatment comprises forming a diffusion aluminide coating on the component surface, wherein the diffusion coating comprises a diffusion sublayer formed on the component surface and an additive sublayer formed on the diffusion sublayer. The method further comprises removing the additive sublayer of the diffusion aluminide coating with at least one aqueous solution such that the diffusion sublayer and the component surface are substantially unaffected, wherein the diffusion layer facilitates preventing coke formation on component surface.
