Problems solved by technology

In addition, it is also very important to improve product quality. The flange filters made of aluminum alloy materials on the market are all small specifications (diameter less than 150mm), and the material is mostly aluminum-silicon (Al-Si), and the aluminum-silicon system has good formability. However, the strength and hardness are low, and it cannot meet its requirements in engineering applications with large diameter, large flow, and high pressure, and it is prone to safety problems such as leakage and rupture.

Description

technical field [0001] The invention relates to the technical field of alloy materials, in particular to an alloy material flange and a preparation method thereof. Background technique [0002] In order to give full play to the superior characteristics of aluminum alloy series represented by "lightness", it must first make great progress in "strength", and at the same time, there must be no unacceptable increase in manufacturing costs, so as to greatly expand its application field. This requires the first breakthrough in the design of new aluminum alloy materials. [0003] From the perspective of material preparation methods, since the characteristics of the material are contributed by the combination of functional microscopic phases bearing the characteristics, a good combination of functional phases is obtained, such as high strength, high melting point, high plasticity, high hardness, Corrosion resistance, etc., are the final results pursued by various preparation method...
