...) Because of friction ( Sec. 3.3 ) and inhomogeneous deformation ( Sec. 2.5 ) in the processing history, the surface of the workpiece is very often deformed to a greater extant than its bulk. The friction process itself can result in extreme cold working of a thin surface layer. This layer is typified...
