Title: Apparatus for deformation of solid sections

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.
