Abstract: A system and method provide a material with uniform micro-structure. In an embodiment, an equal channel angular extrusion system includes an interior mandrel. The interior mandrel includes an expanding shear material section and a contracting shear material section. In addition, the system includes a material. The material is disposed about a portion of the interior mandrel. Moreover, the system includes a pressure application device. The pressure application device applies pressure to the material to force the material to contact the expanding shear material section to provide an expanded post-shear material section. Pressure from the pressure application device applies pressure to the material to force the expanded post-shear material section to contact the contracting shear material section to provide a contracted shear material section.

Abstract: An equal channel angular extrusion tool comprising a punch assembly, a die set assembly, a base assembly, and a bottom slider assembly. The punch assembly comprises a punch, a punch nose, and a punch trolley. The die set assembly comprises an inlet channel and a removable core. The base assembly comprises a lifting mechanism which further comprises a die lift cylinder and a hold down ram. The bottom slider assembly comprises an ejection ram. The tool also includes a billet. The billet may be disposed in the bottom slider assembly. Severe plastic deformation is applied to the billet in the bottom slider assembly.
