| 英文摘要 | We investigated the low-cycle fatigue behavior of a novel nanotwinned 316L stainless steel consisting of nanotwinned austenitic grains embedded in the matrix with characteristic dislocation arrangements. We excitingly found that the alpha\prime-martensitic transformation is activated traversing twin lamellae to undertake the localized deformation of nanotwinned grains at high strain amplitudes. These alpha\prime-Ymartensite nuclei are mainly originated from the intersections between "zigzag" slip bands and twin lamellae. Thanks to the effective release of stress/strain localization by the alpha\prime-martensitic transformation within nanotwins, the fatigue strength and fatigue life in the low-cycle regime are simultaneously enhanced.
