Description

technical field

[0001] The invention relates to the field of powder metallurgy, in particular to a powder metallurgy aluminum-based material and a preparation method thereof. Background technique

[0002] Aluminum alloy is a light material with low density and high specific strength. After aluminum alloy replaces iron-based and copper-based parts, it is beneficial to reduce self-weight, energy saving and emission reduction. Aluminum alloy is used in aerospace, automobile, machinery manufacturing, shipbuilding, and chemical industries. and other fields have been widely used. For example, beams of supersonic fighter jets, high-pressure cylinders, automotive cantilever components, engine blades, casings and cylinder liners, automotive engine and gearbox parts, etc. are widely used in aluminum alloy. However, many parts not only require light weight and good mechanical properties, such as hardness, strength, wear resistance, thermal expansion coefficient, high temperature mecha...
