Mechanical Properties of Several Nickel-Base Alloys at Room and Cryogenic Temperatures
Nickel-base alloys are of particular interest for applications at cryogenic temperatures for a number of reasons. They possess a face-centered cubic crystal structure which is known to retain its toughness down to temperatures approaching absolute zero. Also the nickel-base alloys have excellent high temperature properties, thereby making it possible to have a material which may be employed for structural applications over the temperature range from — 423°F to 1300°-1600°F. The need for such materials in cryogenic fueled, recoverable space vehicles, as well as many other applications, is apparent.
