Shape processes, feedstock materials, conductive materials and/or assemblies

A shear-assisted extrusion process for forming Metal-NCCF extrusions, the process comprising:

• using a die tool, applying a rotational shearing force and an axial extrusion force at an interface of a scroll face of the die tool and a face of a feedstock material, the scroll face of the die tool oriented in a direction generally perpendicular to the axial extrusion force, and comprising spiral grooves to direct plasticized feedstock material toward openings in the scroll face of the die tool;
• wherein the feedstock material comprises a metal and a NCCF (NanoCrystalline Carbon Forms), wherein:
• the metal comprises one or more of Cu, Mg, Al, Fe, Ti, and/or Ni;
• and the NCCF is deposited on the metal;
• and
• wherein the process comprises extruding a mixture comprising the metal and the NCCF through the openings in the die tool to form a Metal-NCCF extrusion comprising a homogeneous distribution of NCCF particles throughout the metal-NCCF extrusion;
• and
• wherein the scroll face of the die comprises a member extending from a center of the scroll face of the die tool.
