technical field [0001] The invention relates to the technical field of metal materials, in particular to a preparation method of a graphene rare earth aluminum alloy high conductivity material. Background technique [0002] With the rapid growth of my country's power transmission volume, the requirements for materials in the transmission process are becoming increasingly stringent. High-quality transmission lines should have the characteristics of long transmission distance, large transmission capacity, and strong resistance to natural disasters. Thermal and sag resistance put forward higher performance requirements for transmission lines. At present, conductor materials made of ordinary aluminum have poor electrical conductivity and heat resistance, and disconnection often occurs during the production process, which increases the production cost and use cost of aluminum alloy conductor materials; aluminum alloy is used as the conductor material , the microstructure in its a...
