Abstract: In some embodiments, a gamma titanium aluminide alloy consists essentially of, in atomic percent, 38 to about 50% aluminum, 1 to about 6% niobium, 0.25 to about 2% tungsten, 0.01 to about 1.5% boron, up to about 1% carbon, optionally up to about 2% chromium, optionally up to about 2% vanadium, up to about 2% manganese, and the balance titanium and incidental impurities. In some embodiments, the gamma titanium aluminide alloy forms at least a portion of a gas turbine component. In some embodiments, a gamma titanium aluminide alloy, consists essentially of, in atomic percent, about 40 to about 50% aluminum, about 1 to about 5% niobium, about 0.3 to about 1% tungsten, about 0.1 to about 0.3% boron, up to about 0.1% carbon, up to about 2% chromium, up to about 2% vanadium, up to about 2% manganese, up to about 1% molybdenum, and the balance titanium and incidental impurities.

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: Provided is a nickel-based coating composition containing cobalt, chromium, aluminum, tantalum, and nickel. The coating composition has a three phase γ, γ′, β microstructure wherein at least 5 volume % of the coating composition is present in the β phase. Also provided are coating systems containing the coating composition, articles having the coating composition or coating system, and methods for protecting nickel-based superalloy substrates using the coating composition or coating system.
