Abstract: A method of bonding superalloys is provided. The method includes: aligning a first superalloy subcomponent having a gamma-prime solvus g′1 and a second superalloy subcomponent having a gamma-prime solvus g′2, with a filler material that includes at least 1.5 wt % boron disposed between the first and second superalloy subcomponents; performing a first heat treatment at a temperature T1, where T1 is above the solidus of the filler material and below the liquidus of the filler material; and performing a second heat treatment at a temperature T2, where T2 is greater than T1, and where T2 is greater than or equal to the lower of g′1 and g′2.

Abstract: A method for joining a filler material to a substrate material 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.
