Nickel alloy and articles |
摘要 |
Articles that include a material that has L12-structured gamma-prime phase precipitates within a matrix phase at a concentration of at least 20% by volume are disclosed. The gamma-prime phase precipitates are less than 1 micrometer in size. The material also has 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 articles may be formed by mechanically working a workpiece that has at least about 40% nickel, about 1.5% to about 8% titanium, and about 1.5% to about 4.5% aluminum. The workpiece may be worked at a temperature below a solvus temperature of the eta phase; and then heat treated at a temperature sufficient to dissolve any gamma prime phase present in the workpiece but below the solvus temperature of the eta phase. |
