The paper reviews the principal paths of modification of the structure and properties of the metallic surfaces by the intense plastic deformation leading to the formation of nanostructure states in the near-surface region. The outcomes of investigations of modified structure and properties of surface layers are considered for both pure metals and different alloys after such ways of intense machining treatment as a vibrational cold-work hardening by globules, sandblasting, processing by the metal hog, repeated rolling, friction, ultrasonic impact processing. The special attention is also given to mechanisms of fabrication of nanoscale structures in depth of modified surface layer as a result of such processings.
Keywords: nanostructure, plastic deformation, vibrational cold-work hardening, friction, ultrasonic impact processing.
