    摘要: Articles suitable for use in high temperature applications, such as turbomachinery components, and methods for making such articles, are provided. The article comprises a material comprising a plurality of L12-structured gamma-prime phase precipitates distributed within a matrix phase at a concentration of at least 20% by volume, wherein the gamma-prime phase precipitates are less than 1 micrometer in size, and a plurality of A3-structured eta phase precipitates distributed within the matrix phase at a concentration in the range from about 1% to about 25% by volume. The solvus temperature of the eta phase is higher than the solvus temperature of the gamma-prime phase. Moreover, the material has a median grain size less than 10 micrometers. The method comprises providing a workpiece, the workpiece comprising at least about 40% nickel, from about 1.5% to about 8% titanium, and from about 1.5% to about 4.5% aluminum. A weight ratio of titanium to aluminum is in the range from about 1 to about 4, and the workpiece further comprises a plurality of A3-structured ordered eta phase precipitates distributed within the matrix phase at a concentration in the range from about 1% to about 25% by volume. The method further comprises mechanically working the workpiece at a temperature below a solvus temperature of the eta phase; and heat treating the workpiece at a temperature sufficiently high to dissolve any gamma prime phase present in the workpiece but below the solvus temperature of the eta phase.

    摘要: A modified alloy is disclosed including a base alloy composition and an additive gamma prime antioxidant. The base alloy composition includes a concentration of a gamma prime antioxidant less than an effective concentration of the gamma prime antioxidant. The additive gamma prime antioxidant is intermixed with the base alloy composition to form the modified alloy, preferentially segregating to a gamma prime phase of the modified alloy and increasing the concentration of the gamma prime antioxidant to be at least the effective concentration of the gamma prime antioxidant. The effective concentration imparts reduced oxidation susceptibility of the gamma prime phase. An article is disclosed including the modified alloy. A coated article is disclosed including a coating disposed on a surface of an article having the base alloy composition. The coated article includes a reduced stress accelerated gamma prime oxidation static crack growth susceptibility in comparison with the base alloy composition.
