Abstract

The invention provides a preparation method of a magnesium base graphene alloy. The method comprises the steps of: preparing mixed powder of graphene and magnesium and/or magnesium alloy, putting the mixed powder into a cover for vacuum degassing, performing hot isostatic pressing, remelting and performing homogenization treatment. According to the method, a certain quantity of magnesium base graphene alloy prefabricated ingot is remelted into magnesium alloy molten liquid; the content of graphene in a composite material is preferably controlled through calculation; as the graphene does not float out, the content in the magnesium base graphene alloy can be accurately controlled; and the preparation method is provided based on semi-continuous casting, and is simple in process operation, high in production efficiency, low in manufacturing cost and easy for realizing large-scale industrialization.

Description

technical field [0001] The invention relates to a preparation method of an olefin alloy, in particular to a preparation method of a magnesium-based olefin alloy. Background technique [0002] Graphene is a new type of two-dimensional nanomaterial. Its nanosheet is a two-dimensional material with a single atomic layer thickness composed of sp2 hybridized carbon atoms. It is the thinnest and hardest nanomaterial known in the world, with a strength as high as 1.01Tpa. , is 100 times that of structural steel, but its density is 1 / 5 of that of structural steel. The thermal conductivity is as high as 5300W / m·K, which is higher than that of carbon nanotubes and diamonds. The electron mobility at room temperature exceeds 200,000cm2 / V·S, which is higher than that of carbon nanotubes or silicon crystals. The resistivity is only about 1Ω·m, which is higher than that of magnesium or silver. Lower, the material with the smallest resistivity in the world. [0003] Graphene is a nano-sca...
