A remarkable improvement of low-cycle fatigue resistance of high-Mn austenitic TWIP alloys with similar tensile properties: Importance of slip mode

Fe-Mn-C TWIP steels manifest a similar tensile deformation behavior with increasing Mn content, while their low-cycle fatigue performances vary significantly. Unlike tensile property, the fatigue performance is extremely sensitive to the slip mode, which has its origin from material's inherent attributions, e.g. stacking fault energy and short range ordering.273
