NOVELTY - Preparing high-performance olefin magnesium alloy involves mixing a surfactant with deionized water to prepare a solution, adding the modified graphene powder to be uniformly mixed, waiting for 10-15 hours, and then drying in a freeze dryer to obtain mixed graphene powder. The magnesium powder and the alloy element powder are smelted under the protection of argon to obtain a molten metal, which is smelted and then kept warm. The temperature is controlled between 160-180 degrees C after the heat preservation, and the mixed graphene powder is added to the molten metal, stirred and mixed uniformly, sonicated for 40-50 minutes, and stirred for 1-2 hours to obtain a molten alloy. The temperature is raised to 700-800 degrees C for slag removal treatment, and then the molten alloy is lowered to 650-680 degrees C, and added to a pre-heated steel mold for casting to obtain an alloy ingot. USE - Method for preparing high-performance olefin magnesium alloy. ADVANTAGE - The method enables to prepare high-performance olefin magnesium alloy, which solves the problem of low dispersibility and easy agglomeration of graphene, and achieves the close combination of graphene and other elements, and has high degree of homogenization and excellent performance in all aspects. DETAILED DESCRIPTION - The alloy ingot is heated to 500-600 degrees C for 6-7 hours, naturally cooled to room temperature, heated to 200-300 degrees C for 10-15 hours, and cooled to obtain the olefin alloy.
