Abstract

The invention relates to a powder metallurgy aluminum-matrix material. The raw material powder comprises, by mass percent, 0.01 to 10% of hydrogenated hafnium powder and the balance aluminum-matrix powder. The aluminum-matrix powder is aluminum elemental powder or aluminum alloy powder or aluminum-matrix composite powder. The invention further relates to a preparing method of the powder metallurgyaluminum-matrix material. The method comprises the following steps of a, powder mixing, b, forming, c, sintering, and d, heat treatment. The powder metallurgy aluminum-matrix material is small in sintering deforming amount, and the preparing method is simple in process, high in production efficiency and suitable for large-batch production.

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...
