1. A method for preparing extruded material by shear assisted processing and extrusion, the method comprising:
applying axial extrusion force and rotational force at an interface of a face of a die tool and a face of a metallic stock material provided in a rotating feedstock container to form an extruded material at a rate between 2 and 13 m/min, wherein:
the face of the die tool comprises at least a portion that is generally perpendicular to the axial extrusion force; and
the portion that is generally perpendicular to the axial extrusion force comprise at least one spiral groove that directs plasticized material of the stock material toward aperture ports of the face of the die tool; and
wherein the metallic stock material is not pre-heated before applying the axial extrusion force and the rotational shearing force.
