Fabrication of Copper-Graphite Multifilamentary Composite Wire by Severe Plastic Deformation Microstructures and Electrical Properties

Copper-carbon composites (where carbon can be graphite, carbon-fibers, fullerenes and carbon nanotubes) are used and under investigations for various applications. The reported manufacturing methods are diverse, but, to our best knowledge, no process is available to fabricate a multifilamentary Copper-Graphite wire with a large number of graphite filaments. We describe a new processing route, which allows the fabrication of such composite by severe plastic deformation. The resulting microstructures and electrical properties are presented and discussed.
