We present the low-cycle fatigue behavior of a new nickel-based superalloy in the temperature range of 650 °C to 760 °C. Two initial microstructures having different precipitate distribution has been chosen for this. Low-cycle fatigue behavior of these two microstructures has been characterized using mechanical parameters. These parameters include cyclic anisotropy, plastic strain accumulation and back stress evolution. The deformation response has been substantiated by detailed electron microscopy studies. A deformation mechanism map illustrating defect activity at various testing conditions has been constructed based on the microscopy results.
