Abstract

The invention relates to the technical field of alloys, and particularly relates to a processing technology of a high-strength AZ91D alloy material. The high-strength AZ91D alloy material comprises the following raw materials in parts by weight: 10 parts of graphene powder, 99 parts of AZ91D powder and 99 parts of attapulgite clay powder. The processing technology particularly comprises the following steps of: S1, taking materials: taking 1 to 10 parts of graphene powder, 80 to 99 parts of AZ91D powder and 1 to 99 parts of attapulgite clay powder; S2, carrying out mixing: placing the raw materials obtained in the S1 into a vertical ball mill to carry out compounding to obtain composite metal powder; and S3, producing a blank: placing the compounded metal powder into a container, and then melting the compounded metal powder and the container into liquid metal in a muffle furnace. According to the invention, the graphene powder and the AZ91D powder are compounded, so that the mechanical properties, such as impact resistance, tensile resistance and the like, of military equipment and aerospace equipment made of the prepared AZ91D composite material are improved, and then the mass of the military equipment and the aerospace equipment is reduced under the condition of ensuring the same firmness, so that the equipment is lighter.
