Metal foam material is a new type of engineering material that integrates physical function and structure. Its excellent physical properties make it widely used in many fields such as sound reduction, shock absorption, separation engineering, catalytic carrier, shielding protection, energy absorption and buffering. Among them, aluminum foam made of rare earth aluminum alloy is also considered to be a promising excellent material for future cars, ships and other means of transportation.

It is understood that the preparation methods of metal foam materials are roughly as follows: powder metallurgy method, which can be divided into two types: loose sintering and reaction sintering; seepage method; sintering dissolution method; melt foaming method; eutectic directional solidification method, etc. Among these many preparation methods, the melt foaming method has the most prospect for industrial large-scale production because of its relatively simple production process and low cost.

The most advanced metal foam materials in the Japanese market are mainly aluminum foam blocks produced by melt foaming method.

The technical difficulties of the melt foaming method are: controlling the viscosity of the melt; Choose the right metal blowing agent. In general, the viscosity of the melt is required, and the foaming agent used is required to bubble quickly near the melting point of the metal.

The first is that its bulk density is about 1 3 of steel, and the specific strength (the ratio of the strength limit to the specific gravity) can meet or exceed that of structural steel. Secondly, aluminum and aluminum alloys are easy to process into various shapes and can adapt to various connection processes, thus providing favorable conditions for the most economical and reasonable cross-sectional form of building structures. Therefore, the use of aluminum alloy can not only greatly reduce the weight of the building, save materials, but also reduce the transportation and installation workload of components, and speed up the construction progress.

This is more significant for the first district and the mountainous and remote areas with inconvenient transportation. Aluminum and aluminum alloys have beautiful color, good corrosion resistance, high reflectivity to light and heat, good sound absorption, and can be obtained in a variety of different colors by chemical and electrochemical methods. Therefore, aluminum is widely used in roofs, walls, doors and windows, skeletons, interior and exterior decorative panels, ceilings, ceilings, railings, interior furniture, store containers and construction formwork in industrial and civil buildings.

The process is divided into two parts: the development of rare earth aluminum alloys; Preparation of rare earth foam aluminum alloys. The development of rare earth aluminum alloy can not only improve the strength of the alloy, but also reduce the melting temperature of the alloy, which is conducive to the preparation of rare earth aluminum foam alloy with high strength.

Under a certain alloy viscosity, it is the key to prepare foam metal by evenly dispersing it into the melt with a suitable foaming agent. In rare earth additives of rare earth aluminum alloys, the rare earth content ranges from: The rare earth foam aluminum alloy is prepared by the melt foaming method, the aluminum alloy is used as the base metal, and the rare earth foam is melted with the self-prepared rare earth additives in the molten state, and the rare earth aluminum alloy melt is obtained, and the metal tackifier and foaming agent are added, and the foaming reaction is carried out in the rare earth aluminum alloy foaming pool, and the rare earth foam aluminum alloy is obtained after molding.

Building products made of aluminium and aluminium alloy materials. It is usually processed into castings, forgings, foils, plates, belts, tubes, rods, profiles, etc., and then made by cold bending, sawing, drilling, assembling, coloring and other processes.

Purified aluminum 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 industries. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy welded structural parts is increasing, and the research on the weldability of aluminum alloy is also deepening. The wide application of aluminum alloy has promoted the development of aluminum alloy welding technology, and the development of welding technology has expanded the application field of aluminum alloy, so the welding technology of aluminum alloy is becoming one of the hot spots in research.

The density of pure aluminum is small (=, about 1 3 of iron, low melting point (660), aluminum is a face-centered cubic structure, so it has high plasticity (δ: 32 40%, 70 90%), easy to process, can be made into various profiles, plates, good corrosion resistance; However, the strength of pure aluminum is very low, and the b value in the annealed state is about 8kgf mm2, so it is not suitable as a structural material. Through long-term production practice and scientific experiments, people have gradually strengthened aluminum by adding alloying elements and using heat treatment, which has obtained a series of aluminum alloys.

Purified aluminum has low density, but relatively high strength, close to or more than high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, is widely used in industry, and the amount of use is second only to steel. The alloy formed by adding certain elements can maintain the advantages of pure aluminum and light weight, and can also have high strength, with b values up to 24 60kgf mm2 respectively. In this way, its "specific strength" (the ratio of strength to specific gravity b) is better than many alloy steels, and it has become an ideal structural material, which is widely used in machinery manufacturing, transportation machinery, power machinery and aviation industry, etc., and the fuselage, skin, compressor and so on of aircraft are often made of aluminum alloy to reduce their own weight.

The welding of aluminum alloy instead of steel plate material can reduce the weight of the structure by more than 50%.

What are the advantages of aluminum profiles, because industrial aluminum profiles have a variety of advantages such as light weight, excellent forming, high strength, corrosion resistance, long life, renewable, less pollution, low maintenance costs, etc., they stand out among many materials and have become the favorite of high-speed rail. The large-scale use of aluminum alloy materials in the carriage has greatly reduced the weight of high-speed rail trains, and has made an important contribution to the high-speed travel of trainsThe high-speed travel of trains is a systematic project, which contains many technical conditions and methods, and the quantification of railway trains is an important way to realize high-speed and heavy loads of trains, that is, under the same conditions, the lighter the weight of the train, the faster the speed.

As early as the 50s of the 20th century, some of the more developed countries in the world began to use aluminum profiles to manufacture railway vehicles, including the United States, Canada, Japan, Russia, Germany and France and other countries. In terms of strength, the strength of pure aluminum is very low, but the alloy formed by adding certain elements has high strength, and the ratio of specific strength strength to specific gravity is better than that of many alloy steels, making it an ideal structural material. The tensile strength of high-strength aluminum alloy is greater than 480 megapascals, which can fully meet the strength standards of high-speed rail train carriages.

At the same time, aluminum alloy has good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, and is widely used in industry.
