Abstract AISI No. 664 is a nickel-base high-temperature alloy that can be precipitation hardened because of its contents of aluminum and titanium. Vacuum melting is used in its production to provide excellent quality and reproducability. It is used for applications requiring a good combination of creep and stress-rupture properties up to about 1500 F. Typical applications are gas-turbine components, airframes and fasteners. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as creep. It also includes information on high temperature performance as well as forming, heat treating, machining, and joining. Filing Code: Ni-269. Producer or source: Nickel alloy producers.

AbstractMulticomponent nickel base intermetallics with the L12 structure were evaluated as high temperature structural materials. The compounds were based on the γ' composition of PWA 1480, a high strength single crystal nickel base superalloy. The best balance of properties in the compound was achieved with <111> oriented single crystals but no significant advantage could be demonstrated over the precipitation hardened superalloys. Insufficient impact resistance was a major deficiency of the L12 compounds. Other nickel base intermetallics were also evaluated but showed little advantage over superalloys.
