Abstract: A method for repairing a part and the resulting is disclosed. The method includes positioning a plug having an inner braze element coupled thereto into a cavity defined by an internal surface of a component. The cavity has a circular cross-section at the external surface of the component. The plug completely fills the circular cross-section and the inner braze element is within the cavity. A braze paste is positioned at least partially around the plug at the external surface. The component is positioned such that the inner braze element is above the plug. The component is subjected to a thermal cycle to melt the inner braze element around the plug, completely sealing the cavity by forming a metallurgical bond with the plug and the internal surface of the component. During the thermal cycle the braze paste is melted to form a metallurgical bond with the plug and external surface.

Abstract: A method of casting a low alloy steel using a mold is disclosed. The method includes receiving the mold having a foam pattern disposed within a sand casing. The received foam pattern is coated with a permeable refractory coating and is disposed between compacted sand and the sand casing. The method further includes pouring a molten metal comprising a low alloy steel having a carbon content in a range from about 0.1 to about 0.4 percent into the mold so as to vaporize the foam pattern and remove gasification products through the permeable refractory coating, to form a low alloy steel casting. Further, the method includes removing the low alloy steel casting from the mold.

Abstract: A method of forming a component having an internal passage defined therein includes positioning a jacketed core with respect to a mold. The jacketed core includes a hollow structure formed from a first material, an inner core disposed within the hollow structure, and a core channel that extends from at least a first end of the inner core through at least a portion of inner core. The method also includes introducing a component material in a molten state into a cavity of the mold, such that the component material in the molten state at least partially absorbs the first material from the jacketed core within the cavity. The method further includes cooling the component material in the cavity to form the component. The inner core defines the internal passage within the component.

Abstract: A mold assembly for use in forming a component having an internal passage defined therein is provided. The component is formed from a component material. The mold assembly includes a mold that defines a mold cavity therein. The mold assembly also includes a lattice structure selectively positioned at least partially within the mold cavity. The lattice structure is formed from a first material that has a selectively altered composition in at least one region of the lattice structure. A channel is defined through the lattice structure, and a core is positioned in the channel such that at least a portion of the core extends within the mold cavity and defines the internal passage when the component is formed in the mold assembly.

Abstract: A mold assembly for use in forming a component having an internal passage defined therein includes a mold defining a mold cavity therein, and a deoxygenated core positioned with respect to the mold. The deoxygenated core includes an inner wall that at least partially defines a sealed core chamber within the deoxygenated core. The sealed core chamber has a substantially reduced oxygen content, and a portion of the deoxygenated core is positioned within the mold cavity such that the inner wall of the portion of the deoxygenated core defines the internal passage when the component is formed in the mold assembly.
