Abstract
An age-hardenable, corrosion-resistant, nickel-base fully dense article of compacted prealloyed particles. The article has a fine, uniformly distributed gamma-prime phase for strength and hardness. The alloy consists essentially of, in weight percent, carbon 0.05 max, chromium 15 to 25, molybdenum 6.5 to 10, columbuium 4 to 6.5, iron 9 max, aluminum 0.2 to 0.8, nitrogen 0.05 max, titanium, 0.6 max, and balance nickel. The alloy article has an absence of interstitial phases at prior particle boundaries and may be age-hardened to a minimum room-temperature 0.2% offset yield strength of 120,000 psi.
