摘要: A composition and process for a nickel-base alloy that exhibits a desirable balance of high-temperature strength and weldability, as well as other properties suitable for high temperature applications. These properties are achieved with an alloy in which the combined level of titanium, aluminum, niobium, and tantalum is carefully controlled. The alloy consists of, by weight, 10 to less than 20% chromium, 15 to 20% cobalt, less than 1.0% molybdenum, 2.5 to 5% tungsten, 1.1 to 1.5% niobium, less than 0.5% tantalum, 3.0 to 3.9% titanium, 2.5 to 3.4% aluminum, 0.07 to 0.15% carbon, less than 0.06% zirconium, less than 0.03% boron, the balance nickel and impurities.
