Abstract

The invention provides a reinforcing aluminium alloy material which comprises the following components in percent by mass: 0.8-1.6% of rare earth ferrosilicon, 3.2-4.5% of copper plated Al2O3-TiC-Co composite powder, 1.5-2.5% of aluminite powder, 0.6-1.2% of magnesium manganese intermediate alloy and the balance of aluminium alloy powder. According to the reinforced aluminium alloy material, a proper amount of rare earth ferrosilicon, the reinforcing material copper plated Al2O3-TiC-Co composite powder and magnesium manganese intermediate alloy are added in aluminium alloy powder to enhance the microhardness and density of aluminium alloy; in addition, the crystal grains can be refined, the surface layer defect is filled, the purity is improved, non-uniform growth of the crystal grains isreduced and local corrosion and the like caused by microscopic unevenness are eliminated.

Description

technical field [0001] The invention belongs to the field of composite materials and alloys, and in particular relates to a reinforced aluminum alloy material. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. Aluminum alloy has low density, but relatively high strength, which is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel. . [0003] Existing aluminum alloys generally have good plasticity but insufficient strength, and their use in some high-strength fields will be limited. On this basis, the present invention provides a reinforced aluminum alloy material. On the ori...
