Abstract

The present invention proposes a method for preparing a high-toughness graphene / ZK61 magnesium alloy composite material. In the preparation method, RGO / ZK61 magnesium alloy powder is calcined by adding GO to ZK61 magnesium alloy powder, and graphene is prepared by spark plasma sintering. / ZK61 magnesium alloy composite material. Compared with the ZK61 magnesium alloy without graphene, the graphene / ZK61 magnesium alloy prepared by this method has significantly improved strength and toughness, and shows strong anisotropy in mechanical properties and structure.

Description

technical field

[0001] The invention belongs to the technical field of composite material preparation, in particular to a preparation method of a high-toughness graphene / ZK61 magnesium alloy composite material. Background technique

[0002] Magnesium alloy is currently the lightest metal structural material in industrial applications. It has the advantages of high specific strength, large specific modulus and easy recycling. It is an internationally recognized green and sustainable material. It is currently used in large aircraft and high-speed rail vehicles. , The light weight structure of electric vehicles has a good application prospect. Magnesium has a hexagonal close-packed lattice structure, and there are only three slip systems at room temperature, resulting in poor plasticity of magnesium-based materials. Crystallization annealing after thermal processing or cold deformation can refine the grains of magnesium-based materials. However, the microstructure of the magne...
