▎ 摘  要

NOVELTY - The method involves applying a rotational shearing force and an axial extrusion to the same location on the feedstock material using a die tool defined by a die face extending from a rim of the die face inwardly at an angle greater than zero in relation to a sidewall of the die tool in cross section. USE - Shear-assisted extrusion method for forming extrusions of desired composition from feedstock material. ADVANTAGE - The method provides a number of benefits including the ability to form materials with better strength and corrosion resistance characteristics at lower temperatures, lower forces, and with significantly lower extrusion force and electrical power than required by other processes. The method results in additional cost saving in addition to a tenfold reduction in power consumption attributed to significantly less force required to produce the extrusions and smaller machinery footprint requirements. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a device for performing shear assisted extrusion; (2) a ShAPE feedstock material; (3) a conductive solid material mixture; and (4) an assembly for relying in portion on conductivity. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of system for forming extrusions of desired composition from feedstock material. Assembly for forming extrusions of desired composition from feedstock material (300) Die tool (302) Feedstock material ring (304) Graphene billet (306) Extrudate material (308)
