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.

Rupture Properties

The creep and creep-rupture properties of 13 heats of annealed 2 1/4 Cr-1 Mo steel were determined at 510 and 566°C (950 and 1050°F). The microstructures of all heats were primarily polygonal ferrite (75–80 percent); the balance was mostly bainite with 1–2 percent pearlite and scattered carbides. At each temperature the results indicated considerable data scatter for the high-stress (short rupture life) tests. As the stress was lowered, the creep and stress-rupture properties converged, which resulted in a decrease in the data scatter. Much of the variation and change in the properties could be attributed to the carbide precipitation reactions that occur in the steel.

Harmful Effects

The influence of certain trace elements, namely Pb, Sn, Te, Se and Tl, on the creep and stressrupture properties of Nimonic 105 was investigated at 815 °C. The work was supported by the Ministry of Defence, and was planned in close collaboration with Rolls-Royce, who advised, in particular, on the trace elements to be studied and the levels at which harmful effects on creep performance might be expected. The results obtained have confirmed that, with the exception of Sn, all the elements reduce the life to rupture and the ductility at failure when present in sufficient amount. The most deleterious impurities were Te and Pb. Stress-rupture testing with notched specimens gave a generally more sensitive indication of the presence of harmful amounts of impurity than did tests with plain specimens.
