Recent Advances in the Equal Channel Angular Pressing of Metallic Materials

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 alloys. ECAP process, can processed severely repeatedly in designed mold accumulate large amount strain. Ultrafine grains with diameters submicron meters or even nanometers achieved through ECAP. detail, paper give state-of-the-art details about influences processing parameters passes, temperature, routes evolution microstructure materials. The sizes, boundaries, phases different during process are also analyzed. Besides, mechanism discussed from perspectives dislocation slipping twinning.
