    Abstract: A method of manufacturing a heat shield panel assembly is provided. The method including: injecting melted wax into a negative cavity of a heat shield panel, the heat shield panel including one or more orifices; allowing the wax to solidify to form a positive pattern of the heat shield panel; removing the positive pattern from the negative cavity; coating the positive pattern with a ceramic; melting the positive pattern away from the ceramic, the ceramic having a cavity forming a second negative cavity of the heat shield panel; pouring melted metal into the cavity; allowing metal in the cavity to solidify to form the heat shield panel; removing the ceramic from the heat shield panel; and forming each of one or more threaded studs separately from the heat shield panel, each of the one or more threaded studs including a stud portion and a thread portion simultaneously formed.

    Abstract: A method of fabricating a casting is provided. The method includes creating a mixture of ceramic powder and a binder, pouring the mixture around sacrificial patterns, executing a first thermal treatment to set the mixture into a solid mold without damaging the sacrificial patterns, executing a second thermal treatment to remove the sacrificial patterns without removing any of the binder from the solid mold, executing at least one of a third thermal treatment and a chemical treatment to remove a quantity of the binder to transform the solid mold into a solid breakaway mold and pouring molten metallic material into the solid breakaway mold.

    Abstract: A system and methods are provided for removing core elements of cast components. In one embodiment, a method includes controlling a first high temperature autoclave cycle for a cast component in a vessel with a first solution concentration to remove at least a first portion of core elements, wherein the first solution concentration, temperature and pressure in the vessel are controlled to expose one or more casting pins in the cast component. The method may also include controlling a second high temperature autoclave cycle for the cast component in the vessel with second solution concentration, wherein the second solution concentration, temperature and pressure in the vessel during the second high temperature autoclave cycle are controlled to loosen one or more of the casting pins from the cast component, and controlling one or more low temperature autoclave cycles to remove core and casting pins from the cast component.

    Abstract: A high-temperature die casting die includes a first die plate with a first recess and a second die plate with a second recess, the first and second recesses defining a main part cavity and gating. A grain selector is in fluid communication with the main cavity, and an in situ zone refining apparatus is adapted to apply a localized thermal gradient to at least one of the first and second die plates. The localized thermal gradient and the at least one die plate are movable relative to each other so as to apply the localized thermal gradient along a first direction extending from the grain selector longitudinally across the main part cavity.

    Abstract: A method for desulfurizing a metal alloy comprises heating the metal alloy to a molten state. A gaseous desulfurizing compound is bubbled through the molten alloy to form a solid sulfur-containing waste phase and a molten reduced-sulfur alloy phase. The solid waste phase and the molten reduced-sulfur alloy phase are separated. The gaseous desulfurizing compound includes a constituent element selected from the group: alkali metals, alkaline earth metals, and rare earth metals.
