OXIDATION RESISTANT LOW EXPANSION SUPERALLOYS |
摘要 |
An oxidation resistant alloy containing iron, cobalt, nickel and at least 4 to 5% by weight aluminum having at least a duplex crystalline structure. One crystalline component of this structure is a gamma (fcc) phase having a gamma prime phase dispersed therein. The second crystalline component is enriched in aluminum compared to the first crystalline component and exhibits characteristics under X-ray diffraction and electron diffraction analysis of a BCC B2 structured phase.
