Abstract (en)
[origin: WO2022219991A1] Provided is a TiAl alloy for forging that makes it possible to obtain a TiAl alloy material having excellent oxidation resistance and high-temperature creep strength, and that has excellent hot forgeability and can be die forged. The TiAl alloy for forging comprises 42.0-43.6 at% of Al, 0.5-2.0 at% of Cu, 3.0-7.0 at% of Nb, and a remainder of Ti and unavoidable impurities.
