Fatigue life improvement through nanostructuring of stainless steel

Abstract : In this paper, the effect of a nanocrystalline surface layer on the fatigue behavior of a 316L stainless steel is investigated. A significant enhance mechanical properties has been achieved through Surface Mechanical Treatment (SMAT). The yield stress and the fatigue limit are noticeably in when compared to those of 316L stainless steel with conventional micrometzr yarn size. All these results are explained in terms of microstructural investigations, X ray diffraction measurements, tensile and fatigue tests, microhardness measurements and residual stress evaluation through the incremental hole drilling method.
