Shot peening is a surface treatment commonly used to improve the fatigue behaviour of mechanical components. It consists in bombarding metallic surfaces with spherical shots to induce plastic deformation in the surface layer of the material. Several researchs have shown that, if applied with unconventional parameters, namely severe shot peening, it can be considered a severe plastic deformation surface treatment, able to strongly modify the microstructure of the surface layer of material by generating grains in the scale of nanometers. In this way it is possible to obtain peculiar physical, chemical and mechanical properties and a superior global behavior with respect of conventional coarse-grained materials. View this paper
