%X Nanostructured layer with a certain thickness and grain size of 10-30 nm was synthesized on a 316L stainless steel by surface mechanical attrition treatment (SMAT) for 60 min. The change of microstructure and properties in the surface layer after cross shear rolling (CSR, 80% reduction) was investigated. The results show that the nanocrystalline structure was still maintained, however, the grain size became finer (5-15 nm) and more uniform and the surface roughness was remarkably reduced. The hardness in the surface layer was slightly increased, but that of the matrix was remarkably increased. The corrosion resistance in 0.05 mol/L H2SO4+0.25 mol/L Na2SO4 solution was improved, but still lower than that of the matrix.
