Abstract: A method is provided for joining a filler material to a substrate material. The method includes melting the filler material within a melting chamber of a crucible such that the filler material is molten. The crucible has an outlet fluidly connected to the melting chamber. The method also includes holding the filler material within the melting chamber of the crucible by applying a first pressure differential across the outlet of the crucible, and releasing the filler material from the melting chamber of the crucible by applying a second pressure differential across the outlet of the crucible to deliver the filler material to a target site of the substrate material. The second pressure differential has a different value than the first pressure differential.

Abstract: A method involves filling a hydrogen-lean molten material in a crucible and closing a lid of the crucible and then feeding a first quantity of a compressed dry gas via the crucible to form a dry gas blanket on a surface of the hydrogen-lean molten material. The method further involves feeding a second quantity of the compressed dry gas to a mold assembly to purge the mold assembly and transferring the hydrogen-lean molten material via an opening of the lid of the crucible to a mold cavity of the mold assembly. The method further involves cooling the hydrogen-lean molten material to form a casting.

Abstract: Methods for joining dissimilar high-temperature alloys are provided, along with articles, such as turbine airfoils, formed by the method. The method comprises interposing a barrier material between a first segment and a second segment to form a segment assembly. The first segment comprises a titanium aluminide material, and the second segment comprises a nickel alloy. The barrier material comprises a primary constituent element present in the barrier material at a concentration of at least about 30 weight percent of the barrier material, and the primary constituent element is a transition metal element of Group 1B, Group 4B (excluding titanium and zirconium), Group 5B, Group 6B, Group 7B, or Group 8B (excluding nickel). The segment assembly is bonded in the solid state at a combination of temperature, pressure, and time effective to produce a metallurgical joint between the first and second segments, thereby forming an intermediate article; and the intermediate article is heat treated to form a bonded article.

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.
