This paper presents materialization through a device of severe plastic deformation process by multiaxial forging. In essence, by design, the device includes a board reinforced with fretting rings where the severe plastic deformation takes place and an assembly, punch-counterpunch that transmits the force from the source and performs multiaxial forging as a discontinuous process. The device has a high level of universality and has the following advantages: contains an extraction system of deformed blank from the active fretted broad; ensures workpiece centering into place of active plate, contains a system for measuring the strength of forging; can be used on any type of press.

Significant Step

Equal Channel Angular Extrusion is a widely adopted severe plastic deformation process capable of imparting large amounts of strain in a material via multiple passes through the die. In order to facilitate reinsertion of worked bars for multipass processing, reshaping is often required. Although this topic is rarely discussed in the literature, it is a significant step that can influence processing efficiency. This paper presents several reshaping options and makes recommendations for method selection based on the authors’ experiences with each.
