Nanostructured metals and alloys processed by plastic deformation are described with emphasis on their structural evolution and on correlations between structure and mechanical properties. Various processes are considered both conventional ones (e.g. rolling, drawing and torsion) and new ones (e.g. accumulative roll bonding, cyclic extrusion compression and equal channel angular extrusion). For all these processes it is a general finding that the structure evolves by subdivision of grains by deformation induced boundaries forming a cell block structure, which refines with increasing strain. A number of structural parameters are defined and analysed leading to qualitative and quantitative correlations between processing parameters and structure and between structural parameters and mechanical properties.
