Materials with ultrafine-grained (UFG) structures can be produced by imparting high plastic strains. For bulk UFG material production, several processing techniques like ECAP have been developed and successfully applied. The handicap of ECAP system is its inconvenience for continuous deformation of aluminum alloy sheets which are widely used as structural components. Dissimilar channel angular pressing (DCAP) is one of the promising techniques used for continuous sheet or strip deformation. In this process, the workpiece is fed into the die by using a feeding roll. The forming die is composed of two intersecting channels, whose thicknesses are different from each other in a way that the thickness of the inlet channel is slightly smaller than that of the outlet channel.
