A processing technique called Equal Channel Angular Pressing (ECAP) has been used for many metals and alloys to impose severe plastic deformation, and therefore create extreme dislocation densities. However, the primary purpose of ECAP is not to create high strength by severe work hardening. What is the main reason to perform ECAP processing, and why is the technique particularly attractive for this purpose?

Strengthening of Alloys

Strengthening of the alloys is required as metals become weak due to various lattice defects, metal bonding phenomena. The strength of the metals is not enough for any mechanical work. The internal dislocations of any metals arise due to forming processes. Due to the movement of these dislocations, the metals are plastically deformed.
