    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: Embodiments of the disclosure provide a system including: an enclosure having an interior sized to enclose and the workpiece and form a vacuum and pressurized atmosphere within the interior. A plurality of thermal applicators may be in thermal communication with first and second portions of the interior. First and second thermal applicators may independently heat and cool the first and second portions of the interior. The first thermal applicator may apply a first thermal treatment to a first portion of the workpiece in the first portion of the interior. A second thermal applicator may apply a second thermal treatment to a second portion of the workpiece in the second portion of the interior independently of the first thermal treatment.

    Abstract: A cast nickel-base superalloy that includes iron added substitutionally for nickel. The cast nickel-base superalloy comprises, in weight percent about 1-6% iron, about 7.5-19.1% cobalt, about 7-22.5% chromium, about 1.2-6.2% aluminum, optionally up to about 5% titanium, optionally up to about 6.5% tantalum, optionally up to about 1% Nb, about 2-6% W, optionally up to about 3% Re, optionally up to about 4% Mo, about 0.05-0.18% C, optionally up to about 0.15% Hf, about 0.004-0.015 B, optionally up to about 0.1% Zr, and the balance Ni and incidental impurities. The superalloy is characterized by a γ′ solvus temperature that is within 5% of the γ′ solvus temperature of the superalloy that does not include 1-6% Fe and a mole fraction of γ′ that is within 15% of the mole fraction of the superalloy that does not include 1-6% Fe.

    IPC: C22C19/05

    Abstract: A composition of matter includes from about 16 to about 20 wt % chromium, greater than 6 to about 10 wt % aluminum, from about 2 to about 10 wt % iron, less than about 0.04 wt % yttrium, less than about 12 wt % cobalt, less than about 1.0 wt % manganese, less than about 1.0 wt % molybdenum, less than about 1.0 wt % silicon, less than about 0.25 wt % carbon, about 0.03 wt % boron, less than about 1.0 wt % tungsten, less than about 1.0 wt % tantalum, about 0.5 wt % titanium, about 0.5 wt % hafnium, about 0.5 wt % rhenium, about 0.4 wt % lanthanide elements, and the balance being nickel and incidental impurities. This nickel-based superalloy composition may be used in superalloy articles, such as a blade, nozzle, a shroud, a splash plate, a squealer tip of the blade, and a combustor of a gas turbine engine.

    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.
