Abstract
Nano materials are being increasingly used in industrial applications as structural components or functional devices. Mechanical reliability is one of the critical issues with respect to these materials. This paper gives an overview of the different research projects relative to the field of surface nanocrystallization (SNC) of metallic materials during last years. Different patented routes of processing of the SMAT (Surface Mechanical Attrition Treatment) and their effect on the mechanical behavior will be presented.
