    Abstract

    The stress-strain behavior of a Fe-Ni-Cr alloy during in-phase and out-of-phase tests under conditions synchronizing thermal cycling with mechanical cycling has been studied by using a specially designed thermal cycling unit. The curves of cycling stress, strain, and temperature versus time indicate that the thermomechanical cycling softening phenomenon occurring in the higher-temperature region, close to the maximum thermal cycling temperature, is a common characteristic under thermomechanical cycling in-phase and out-of-phase superposition tests. However, a difference in behavior between in-phase and out-of-phase is evident. The tests show that the thermomechanical cycling softening occurred in the tensile strain range for in-phase testing and occurred in the compressive strain range for out-of-phase.
