Analysis of cyclic plastic response of nickel based IN738LC superalloy

Cyclic strain controlled tests with blocks of stepwise increasing strain amplitudes were applied to cylindrical specimens of cast Inconel 738LC superalloy at 23 and 800°C in laboratory atmosphere. Cyclic hardening/softening curves and shortened cyclic stress–strain curves were obtained at both tempe...
