Description

technical field [0001] The invention relates to a metal layered composite material and a preparation method thereof, in particular to a graphene-enhanced light metal layered composite material and a preparation method thereof. Background technique [0002] Metal layered composite material refers to a material formed by the metallurgical combination of two or more metals using material composite technology. The dissimilar metals in the metal layered composite material are distributed in layers, which have better performance than each single metal, forming a composite effect. The combination of different metals can be rationally used to make the metal layered composite material have special properties, so it has broad application prospects in many special fields. [0003] Magnesium and magnesium alloys are currently one of the lightest metal structural materials in practical applications, with low density, high specific strength and specific stiffness, good high temperature r...
