The significance of powder-metallurgy process for the development of aluminum alloy materials
|I do not know since when I have been researching the aluminum alloy materials used in the military or special industries. In the process, I have also gained a lot, and developed and produced a variety of aluminum that meets China’s national conditions. Alloys and extruded materials basically meet the needs of national defense military industry, national economic construction, and people’s livelihood.|
But what does this have to do with powder metallurgy? Mainly because the overall level and independent research and development capabilities of aluminum alloy materials are still far from the international advanced level.
In order to reduce the gap, the powder metallurgy process has played a key role.
If you want to improve traditional aluminum alloy materials, you must rely on a series of advanced technologies and theories, such as microalloying theory, electronic metallurgy technology, etc. Powder metallurgy technology is included to adjust the content and proportion of alloying elements and add high-efficiency element.
At the same time, it is necessary to study the strengthening theory, develop the deformation heat treatment process and the new technology of efficient purification, purification, refinement and homogenization, so as to achieve the purpose of changing the traditional aluminum alloy.
Under the operation of a variety of advanced technologies, we can develop more high strength, high toughness, high mold, wear resistance, corrosion resistance, fatigue resistance, high temperature resistance, low temperature resistance, radiation resistance, fire protection, explosion protection, easy cutting, easy polishing, It can be surface treated, weldable and ultra-light aluminum alloy materials and extruded products to meet the needs of different uses, various properties and functions.
But at the same time, it is necessary to research and develop various heat treatments, deformation heat treatments and surface treatments for aluminum alloys to obtain various materials with special properties and functions.
Even though the role of powder metallurgy is very new, we still need to deeply study the powder metallurgy, spray forming, composite materials, ultrafine powders and nano-scale materials of aluminum alloys, and seek greater breakthroughs.
