Abstract
Interim results of Alloy 718 physical and mechanical properties testing are reported. All tests were performed on material given the 954°C solution anneal and 718/621°C duplex age. Tests were conducted in air and included determinations of electrical resistivity, thermal conductivity, thermopower, differential thermal expansion, mean thermal expansion, Young's modulus, shear modulus, Poisson's ratio, tensile properties, creep-rupture properties, low-cycle and high-cycle fatigue properties, notch effects on fatigue behavior, creep-fatigue interaction, cyclic stress-strain and Charpy impact behavior. All properties were measured from 24 to 760°C except for fatigue; fatigue tests were conducted from 24 to 649°C.Keywords
