  • Patent number: 12000020
    Abstract: Any metal having a low ?-ray emission, the metal being any one of tin, silver, copper, zinc, or indium, wherein an emission of an ?-ray after heating the metal at 100° C. in an atmosphere for six hours is 0.002 cph/cm2 or less. Any metal of tin, silver, copper, zinc and indium each including lead as an impurity is dissolved to prepare a hydrosulfate aqueous solution of the metal and lead sulfate is precipitated and removed in the solution. The lead sulfate is precipitated in the hydrosulfate aqueous solution by adding a lead nitrate aqueous solution including lead having an ?-ray emission of 10 cph/cm2 or less to the hydrosulfate aqueous solution, from which the lead sulfate has been removed, and, at the same time, the solution is circulated while removing the lead sulfate to electrowinning the metal using the hydrosulfate aqueous solution as an electrolytic solution.

  • Publication number: 20150000799
    Abstract: The present application discloses wrought 2xxx Al—Li alloy products that are work insensitive. The wrought aluminum alloy products generally include from about 2.75 wt. % to about 5.0 wt. % Cu, from about 0.2 wt. % to about 0.8 wt. % Mg, where the ratio of copper-to-magnesium ratio (Cu/Mg) in the aluminum alloy is in the range of from about 6.1 to about 17, from about 0.1 wt. % to 1.10 wt. % Li, from about 0.3 wt. % to about 2.0 wt. % Ag, from 0.50 wt. % to about 1.5 wt. % Zn, up to about 1.0 wt. % Mn, the balance being aluminum, optional incidental elements, and impurities. The wrought aluminum alloy products may realize a low strength differential and in a short aging time due to their work insensitive nature.

    Abstract: A damper for a gas turbine engine is provided. The damper comprises a first portion, a second portion, and a surface. The second portion angularly extends from the first portion to define an interior corner therebetween. The surface bounds the first portion, the second portion, and the interior corner. The damper further comprises a grain composition containing columnar grains and equiaxed grains. The equiaxed grains are disposed adjacent to the surface such that a volume of the columnar grains is less than a volume of the equiaxed grains in the grain composition.

    Abstract: Disclosed is an apparatus for loading one or more alloy ingots into a molding machine. The apparatus includes a holder configured to hold a plurality of the alloy ingots and dispense one or more of the alloy ingots into a melt zone of the molding machine through an opening in a mold of the machine. The holder is moved in a perpendicular direction with respect to an axis along a center of the opening in the mold between a first position in line with the opening in the mold to dispense one or more of the alloy ingots and a second position away from the opening in the mold. The apparatus can carry ingots of amorphous alloy material so that when the machine melts and molds the material, it forms a bulk amorphous alloy containing part.
