Abstract Scope The monotonic and cyclic behavior of 316L stainless steel (SS) with a gradient nanostructured (GNS) layer was investigated. The GNS layer was obtained using surface mechanical rolling treatment (SMRT). The plastic deformation levels achieved during the SMRT induced severe grain refinement, residual stresses, and martensitic phase transformation. The monotonic tensile strength of the SMRT 316L SS is increased by 13% and the elongation at failure is decreased by 25%, compared to the coarse-grained (CG) untreated specimen. Strain-controlled tension-compression fatigue tests were performed in both SMRT and CG specimens. The fatigue properties of the SMRT specimens are significantly enhanced, compared to the CG specimens. Furthermore, surface and subsurface fatigue crack initiation are observed, depending on the strain amplitude. The mechanisms involved in the enhancement of the fatigue properties due to the SMRT are discussed.
