In recent years, research on ultra-fine grain materials has gained attention. While attempts have been made to improve the properties of material, it also become increasingly important decrease costs. Studies improving material revealed new production methods or required revision existing methods. this direction, severe plastic deformation come fore as a good alternative, and by with variations...

Applications of a metallic material highly depend on its mechanical properties, which greatly the material’s grain sizes. Reducing sizes by severe plastic deformation is one efficient approaches to enhance properties material. In this paper, equal channel angular pressing (ECAP) will be reviewed illustrate effects refinement some common materials such as titanium alloys, aluminum and magnesium ...
