Cyclic Deformation Behavior of Haynes 188 Superalloy Under Axial-Torsional, Thermomechanical Loading

Source

Four types of axial-torsional, thermomechanical fatigue experiments have been performed on Haynes 188 superalloy: mechanically in-phase and thermally in-phase, mechanically in-phase and thermally out-of-phase, mechanically out-of-phase and thermally in-phase, and mechanically out-of-phase and thermally out-of-phase. In this study, representative cyclic deformation behavior of the axial-torsional, thermomechanical experiments is presented and compared with isothermal experiments performed at the two temperature extremes (316°C and 760°C) of the thermal cycle. The evolution of cyclic hardening under axial-torsional, thermomechanical conditions is also presented and compared with the corresponding isothermal data.
