Equal channel angular rolling based on the equal channel angular pressing is a severe plastic deformation process. This process has been developed to overcome the limitations of discontinuity and the lack of using strips in the equal channel angular pressing process. This process has the ability to apply severe shear deformation and fabricate ultra-fine grained structure, as well as improve the material properties of thin sheets without changing the dimensions. Process parameters such as rolling pass number and route have been investigated to analyze the mechanical behavior of materials. In the present study, the impact of equal channel angular rolling process on the mechanical properties such as yield and tensile strength, elongation and microhardness in different alloys of materials is briefly summarized by focusing on the effect of pass number and rolling route. Despite the improvement of mechanical properties in sheets by repeating the number of equal channel angular rolling process passes, repeating more than three process passes to improve the properties does not seem logical.
