  • Patent number: 9322090
    Abstract: Components and methods of processing such components from precipitation-strengthened alloys so that the components exhibit desirable grain sizes following a supersolvus heat treatment. The method includes consolidating a powder of the alloy to form a billet having an average grain size. The billet is then forged at a temperature below the solvus temperature to form a forging having an average grain size of not coarser than the grain size of the billet. The billet is then forged at a total strain of at least 5%, after which at least a portion of the forging is heat treated at a temperature below the solvus temperature to pin grains within the portion. The entire forging can then be heat treated at a temperature above the solvus temperature of the alloy without coarsening the grains in the portion.

  • Patent number: 9260673
    Abstract: A method for operating a gasifier includes detecting a corrosive compound between a combustion chamber defined within the gasifier and an inner wall of a pressure vessel that at least partially surrounds the combustion chamber via a corrosion sensor and increasing the temperature of the inner wall of the pressure vessel to a temperature that is greater than a dew point of the corrosive compound via a heater that at least partially surrounds the pressure vessel. The method may also include adjusting a flow of at least one of a fuel, an oxidant and a diluent to the gasifier in response to the detection of the corrosive compound so as to modify the dew point of the corrosive compound.

  • Patent number: 8991611
    Abstract: A method of separating a powder mixture is disclosed. A first magnetic field is applied to the powder mixture which may contains a non-magnetic metal powder and a contaminant powder. A field strength of the first magnetic field magnetizes the non-magnetic metal powder and leaves the contaminant powder non-magnetized. A second magnetic field is applied to the powder mixture to separate the magnetized metal powder from the non-magnetized contaminant powder.

  • Patent number: 8714233
    Abstract: A casting process for producing metal alloy castings, facecoats and apparatuses suitable for carrying out the process, and castings produced by the process. The casting process entails the use of a mold having a cavity with a continuous aluminum-containing solid facecoat on its surface. A molten quantity of a metal alloy is introduced into the mold cavity so that the molten alloy contacts the solid facecoat. The mold is then allowed to cool to solidify the molten alloy and form a cast product. During the casting process, aluminum in the solid facecoat diffuses into the cast product to form an aluminum-containing surface region at the casting surface. Following removal of the cast product from the mold, an alumina-containing scale grows on the casting surface as a result of oxidation of the casting surface region.
