Abstract

The invention provides a composite reinforced aluminum magnesium alloy material. A preparation method comprises the following steps that aluminum ingots are put into a crucible in a resistance furnace and heated until the aluminum ingots are completely molten; magnesium ingots are added in batches and stirred, and after the magnesium ingots are completely added, a spiral stirring rod is adopted for stirring; the stirring speed continues to be increased, gold nanoparticles based on a biological template and silkworm excrement biochar loaded silicon particles are slowly added into the melt by utilizing eddy current formed by stirring to be stirred; and after the temperature of the melt is steady, ultrasonic treatment is conducted, the temperature of the melt is increased to 750 DEG C after treatment, and the melt is subjected to heat preservation and then poured into a mold to obtained the composite reinforced aluminum magnesium alloy material. A new structure is introduced into the composite reinforced aluminum magnesium alloy prepared by the invention, the adopted particle reinforcements are not prone to agglomeration and have good compatibility with the aluminum magnesium alloy, and most importantly, the prepared material is good in mechanical property and has very high application value on clean-keeping surfaces of satellite antennas and radars, as well as the surfaces of aeronautical materials, automobile shells and the like.

Description

technical field [0001] The invention relates to the field of alloy materials, in particular to a composite reinforced aluminum-magnesium alloy material. Background technique [0002] With the rapid development of modern industry and technology, the requirements for materials in various fields of the country are becoming more and more stringent. It is difficult for a single material to meet the needs of various special properties, and the emergence of composite materials has solved this problem. Metal matrix composites can fully explore the excellent properties of the matrix and the reinforcement, and at the same time promote each other, overcome the shortcomings of a single material, and compound a new type of material with good comprehensive performance. It has been used in national aerospace, national defense, transportation, etc. Major fields have attracted widespread attention. The performance of aluminum-magnesium-based composite materials is particularly outstanding, ...
