Material Notes:
A mechanically alloyed nickel-chromium alloy with oxide dispersion strengthening. Mechanical alloying, which involves high-energy milling of metal powders, is used to create a uniformly distributed, fine dispersoid of yttrium oxide in the alloy. The dispersoid, which is stable to the alloy's melting point, imparts exceptional high-temperature strength and creep resistance. The alloy's strength, corrosion resistance, and microstructural stability make it useful for gas-turbine vanes and other extreme-service applications. Standard product forms are round, flats, extruded section, plate, and wire.Data provided by the manufacturer, Special Metals.
