This structural variation influences many characteristics of UFG metals and have 2-4 times greater strength. The forming techniques and the properties of nanostructured and UFG materials transformed by Severe Plastic Deformations (SPD) methods become the recent studies lately [1]. According to the techniques of SPD, Equal Channel Angular Pressing (ECAP) owns the usefulness of great samples production [2] and has the ability to commercialize [3]. It was proposed by Segal et al. [4] and later developed by Valiev et al. [5, 6] for achieving ductility In this method, as illustrated in Fig. 1, a billet may be pressured by a die that has two angles channel angle and an outer arc of curvature ψ. An equivalent strain of 1 is obtained [1]. A major advantage achieved in equal-channel angular extrusion (ECAE) is the unchanged cross-area of the extruded material .This means that the material might have a chance to be malformed to obtain a high total strain [7, 8].
