摘要： A yttrium-free, nickel-chromium-iron-aluminum alloy characterized by excellent oxidation resistance at very high temperatures. The alloy consists essentially of, by weight, from 14 to 18% chromium, from 4 to 6% aluminum, from 1.5 to 8% iron, up to 12% cobalt, up to 1% manganese, up to 1% molybdenum, up to 1% silicon, up to 0.25% carbon, up to 0.03% boron, up to 1% tungsten, up to 0.5% tantalum, up to 0.2% titanium, up to 0.5% hafnium, up to 0.2% zirconium, up to 0.2% rhenium, balance essentially nickel. The nickel plus the cobalt content is at least 66%.
