Abstract— Equal Channel Angular Pressing (ECAP) has been increasingly recognized due to the inimitable physical and mechanical properties inbuilt in various ultrafine grained materials. It is known that ECAP involves perfectly homogeneous large simple shear plastic deformation within a work piece pressed through a die containing two intersecting channels of identical cross-section. This Paper offers a brief summary of the effect of die geometry and processing route on aluminum alloys processed through ECAP which entails a deformation process on the material. Various factors have been known to affect the properties ECAPed materials like type of route, die geometry to control the properties of aluminum material. Die geometry is considered to be channel angle, corner angle and type of routes are followed in ECAP is Route A, Route BC, Route BA, Route C. These characteristics effects are to be discussed in this paper.
