Description

technical field [0001] The invention relates to a preparation method of a graphene-reinforced magnesium-based composite material, in particular to a deep supercooling preparation method of a graphene-reinforced magnesium-based composite material. Background technique [0002] Under the existing technical conditions, the preparation of graphene-reinforced magnesium-based composite materials is mainly carried out by powder metallurgy. However, practice has shown that the existing preparation methods have the following problems due to their own limitations: First, the existing preparation methods are difficult to ensure the close combination of graphene and magnesium alloy, which leads to poor metallographic compactness of the produced product on the one hand. On the other hand, there are a large number of shrinkage cavities and shrinkage defects in the manufactured products, resulting in poor surface quality and mechanical properties of the manufactured products. Second, the ...
