Constitutive modelling of ratcheting behaviour for nickel-based single crystal superalloy under thermomechanical fatigue loading considering microstructure evolution

•The microstructure evolution of a single crystal superalloy under IP TMF and OP TMF is investigated.•Phenomenological models are developed to describe the microstructure evolution.•A modified crystal plasticity constitutive model considering microstructure evolution is developed.•Ratcheting behavio...
