NOVELTY - Performing high-strength AZ91D alloy material processing technology involves using 10 pts. wt. graphene powder, 99 pts. wt. AZ91D powder, 99 pts. wt. attapulgite clay powder. The raw materials are placed into vertical ball mill for compounding to obtain composite metal powder. The composite metal powder is placed into container, and melted into liquid metal in muffle furnace together with container. The liquid metal is poured into rectangular mold for cooling, and after metal in rectangular mold is formed, demolded from container to form composite metal solid embryo. The composite metal solid body is placed in electric furnace for heating, and placed on electric screw press for forging to obtain forging. USE - Method for performing high-strength AZ91D alloy material processing technology used for manufacturing military equipment and aerospace equipment. Uses include but are not limited to aircraft, watercraft, and hybrid vehicles. ADVANTAGE - The method enables to provide high strength AZ91D alloy material with improved mechanical properties such as impact resistance and stretch resistance of aerospace equipment, ensures the same firm state, so as to reduce the quality, making the device more portable, eliminates the defect in the composite metal solid blank, optimizes the microstructure structure, controls the internal tissue of the composite material, makes the prepared military equipment, and the structural performance of the aerospace equipment is more stable. DETAILED DESCRIPTION - Performing high-strength AZ91D alloy material processing technology involves using 10 pts. wt. graphene powder, 99 pts. wt. AZ91D powder, 99 pts. wt. attapulgite clay powder. The raw materials are placed into vertical ball mill for compounding to obtain composite metal powder. The composite metal powder is placed into container, and melted into liquid metal in muffle furnace together with container. The liquid metal is poured into rectangular mold for cooling, and after metal in rectangular mold is formed, demolded from container to form composite metal solid embryo. The composite metal solid body is placed in electric furnace for heating, and placed on electric screw press for forging to obtain forging. The forging is placed in melting furnace for melting, used colander to remove upper layer of scum. The molten metal after removing slag is placed into mold, and crushed mold while adding, and demoulded to obtain semi-finished workpiece. The semi-finished workpiece is calcined to 400-500degrees Celsius, and cooled in prepared molten salt for cooling. The semi-finished workpiece after quenching is placed into vacuum nitriding furnace and energized, and closed furnace door when rises from room temperature to 200degrees Celsius. The vacuum until pressure in furnace is 0.1-minus 0.06 megapascal. The peak of nitriding reaction occurs during period of 400-450degrees Celsius. The interval nitrogen charging is performed. The composite is obtained after cooling finished material. The newspaper is brushed with oil, dried in sun to make greased paper, and wrapped finished composite material in dried greased paper.
