“…For more general applications, it is necessary to consider the additional impact on crack initiation and growth of gradients in near-surface microstructure, mechanical properties and residual stress induced by the machining and grinding processes. Machined and ground surfaces will often exhibit a near-surface microstructure (figure 13) that is characterized by a very small grain size on the scale of nanometres, perhaps 50-100 nm, with a depth that is dependent on surface preparation history [31,44]. Slip lines can also be observed to extend to depths of about 20 µm.…”

“…Most of UFG materials in the list are pressed by ECAP, HPT, ARB as the core of SPD technology, but the recent emerging SPD for surface modi cation such as surface mechanical attrition treatment (SMAT), 21,[72][73][74] cryorolling, 75,76) high-power shotblast, [77][78][79][80][81] burnishing, [82][83][84] friction stir processing (FSP) 85,86) are included. However, nanocrystalline metals, which are fabricated by the so-called bottom-up approaches such as magnetron and DC spattering, powder consolidation by high-energy ball milling are excluded in this Better=Corrosion resistance increases with grain size reduction, Worse=Vise versa.…”

“…In SCC tests, the bending of flat bar austenitic stainless steel also contributes to the tensile or compressive stresses as the applied load and the grinding leads to tensile residual stresses usually at the outer surface layers [4]. According to A. Turnbull, the tensile residual stress at the surface layer affects the stress corrosion cracking (SCC) behavior by surface machining or grinding [5].…”
