Abstract

A gamma titanium aluminide alloy consisting of, in atomic percent, 38 to 50% aluminum, 1 to 6% niobium, 0.25 to 2% tungsten, 0.01 to 1.5% boron, up to 1% carbon, optionally up to 2% chromium, optionally up to 2% vanadium, up to 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 (110,112). In some embodiments, a gamma titanium aluminide alloy, consists of, in atomic percent, 40 to 50% aluminum, 1 to 5% niobium, 0.3 to 1% tungsten, 0.1 to 0.3% boron, up to 0.1% carbon, up to 2% chromium, up to 2% vanadium, up to 2% manganese, up to 1% molybdenum, and the balance titanium and incidental impurities.
