By means of surface mechanical rolling treatment (SMRT), a gradient nanostructured (GNS)
surface layer was formed on AISI 316L stainless steel. The mean grain size is∼ 30 nm in the …

Most of the challenges experienced by many engineering materials originate from the
surface which later leads to total failure, hence affecting the resultant mechanical properties …

Cyclic stresses are often related to the premature mechanical failure of metallic biomaterials.
The complex interaction between fatigue and corrosion in the physiological environment has …

Severe shot peening aimed to generate a nanograined layer over specimens' surface has
been applied by means of standard air blast equipment but using peening parameters …

Abstract Effect of nanocrystalline surface obtained by severe plastic deformation on fatigue
strength of nodular cast iron has been studied in the paper. Surface nanocrystallization has …

Systematical microstructure characterization, mechanical testing and constitutive modeling
were carried out to quantify the effects of residual stress and grain refinement on tensile …

Nanocrystalline metals have been shown to exhibit unique mechanical behavior, including
