The alloy has an aged microstructure and an ultimate tensile strength of at least about 1100 MPa and a Charpy V-notch toughness of at least about 69 J. In one embodiment, the aged microstructure includes martensite and not more than about 10% reverted austenite. In another embodiment, the alloy includes substantially all martensite and substantially no reverted austenite. The alloy is useful for making turbine airfoils.
