Abstract : This report deals with the physical and mechanical properties of 21 commercial alloys that are candidates for flywheel rotors used as inertial-energy-storage systems. Base metals include aluminum, iron and titanium. Alloys vary in complexity from simple carbon steels to superalloys. Properties include: mass density, Young's modulus, shear modulus, bulk modulus, Poisson's ratio, yield strength, ultimate strength, fatigue strength, fracture toughness, and creep strength. Property values were collected from many types of sources and were analyzed statistically to detect possible outlying values. For each alloy, the report contains typical chemical composition, typical heat treatment, metallurgical descriptions, and typical property values. The report also shows the variations of these properties and the relative abundances of experimental property values. (Author)
