Title:
GRAPHENE/COPPER COMPOSITE DEFORMED COPPER-CHROMIUM-ZIRCONIUM ALLOY LAYERED STRIP MATERIAL, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/123859
Kind Code:
A1
Abstract:
A graphene/copper composite deformed copper-chromium-zirconium alloy layered strip material and a preparation method therefor. An embodiment comprises: first carrying out ambient temperature equal channel angular pressing (ECAP) and cryogenic rolling (CR) on a block-shaped copper-chromium-zirconium alloy having undergone solution treatment; then performing electrodeposition treatment for graphene composited with copper on copper-chromium-zirconium alloy strip material having undergone deformation; then stacking the composite strip material and performing cold rolling, obtaining a layered strip material, and finally performing vacuum aging treatment. The composite material has an electrical conductivity reaching 75-85 % IACS, a tensile strength reaching 600-850 MPa, a thermal conductivity reaching 600-1200 W/m-K, a percentage elongation at break reaching 10-20%, and said composite material fulfills usage in the fields of electrical conduction and heat transfer.
