Description
Technical Field
The invention belongs to the technical field of aluminum-based composite materials, and particularly relates to a preparation method of a high-toughness in-situ particle reinforced aluminum alloy-based composite material.
Background
3003 aluminum alloy has good corrosion resistance, excellent weldability and excellent press workability due to the addition of Mn, Fe, Si and other elements. It is often used in air conditioners, refrigerators, radiators, etc. However, the 3003 aluminum alloy has lower strength, so that the possibility of thinning the aluminum alloy as a radiating fin is limited, and the subsequent research and improvement are not facilitated. We have investigated the preparation of in situ Al 2 O 3 Particle reinforced 3003 aluminum alloy based composites improve this situation.
The particle reinforced aluminum matrix composite material prepared by the in-situ method has excellent mechanical property, good oxidation resistance and corrosion resistance due to small size of reinforced particles and clean bonding interface with a matrix. Compared with an external method, the bonding strength of the composite material and a matrix interface is higher, and the wettability is better. Therefore, the method has great development prospect in important fields of aerospace, national defense and the like.
The most common reinforcing particles currently used in-situ aluminum-based composite materials are Al 2 O 3 TiC and TiB 2 Etc. of Al 2 O 3 The grain hardness is higher, so that the composite material taking the grain hardness as the reinforcing phase has high specific strength and specific modulus and good wear resistance, and the in-situ Al is used 2 O 3 The particle reinforced aluminum matrix composite material has higher application value.

China ranks kaolin mineral resources in the top of the world, has already ascertained 267 mineral production areas and ascertains the reserve volume of 29.10 hundred million tons. The theoretical chemical composition of kaolin is 46.54% SiO 2 39.5% of Al 2 O 3 13.96% of H 2 O, kaolin minerals belong to the 1:1 type phyllosilicates. The kaolin is calcined in a calcining furnace to a certain temperature and time, and the structural water is removed, so that the physical and chemical properties of the kaolin are changed to meet certain use requirements.
The existing in-situ system reaction has some problems, such as particle agglomeration, difficult control of the generated particle size and the like. The mechanical stirring process drives the melt to flow ceaselessly through a stirring device, so that the distribution of internal particles is changed. However, it is difficult to disperse the reactants uniformly in the melt by ordinary mechanical stirring.
