Graphene/copper composite deformed copper-chromium-zirconium alloy layered strip and preparation method thereof

Abstract

A method for preparing a graphene/copper composite deformed copper-chromium-zirconium alloy layered strip is provided. The method includes: obtaining a deformed copper-chromium-zirconium alloy strip by performing a solid solution treatment on a bulk copper-chromium-zirconium alloy, and performing a room temperature equal channel extrusion and a low temperature rolling on the bulk copper-chromium-zirconium alloy after the solid solution; obtaining a graphene/copper composite deformed copper-chromium-zirconium alloy strip by preparing a graphene/copper composite deposition liquid and performing a surface electrodeposition treatment on the deformed copper-chromium-zirconium alloy strip; obtaining the graphene/copper composite deformed copper-chromium-zirconium alloy layered strip with a rolling deformation of 65%-95% by stacking the graphene/copper composite deformed copper-chromium-zirconium alloy strips for 3-7 layers, and then performing a cold rolling, a single rolling deformation being 5%-10%; and performing a vacuum aging on the graphene/copper composite deformed copper-chromium-zirconium alloy layered strip.
