title = "Surface nanocrystalline metallic materials fabricated by near surface severe plastic deformation",
abstract = "The present authors have succeeded in fabricating the surface nanocrystalline materials, in which only subsurface layers have nanocrystalline structures, by near surface severe plastic deformation (NS-SPD) process using simple wire-brushing. Nanocrystals with mean diameters smaller than 100 nm formed at surface layers of various kinds of metallic materials after the NS-SPD processing at ambient temperature. In case of a commercial purity aluminum, the depth of the nanocrystalline layer was about 15 nm from the surface. The surface nanocrystalline aluminum performed significantly higher proof stress than that of the coarse grained material without nanocrystalline surface. Possibility to fabricate surface non-equilibrium materials by the present NS-SPD was also examined.",
