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.
