With the increasing demand for high-quality products in the manufacturing industry, the production technology of magnesium alloy forgings is also improving. Among them, magnesium alloy semi-solid thixoforming technology, as a cutting-edge forming technology, has shown great potential in improving the quality of forgings. This paper introduces the principle, advantages and application of semi-solid thixoforming technology of magnesium alloy in high quality forging production.
The semi-solid thixoforming technology of magnesium alloy is a kind of forming process in the semi-solid state of magnesium alloy. In the semi-solid state, magnesium alloys have both the deformability of solids and the fluidity of liquids. By precisely controlling the temperature and stress conditions, the thixotropy of magnesium alloy in semi-solid state can be realized, and the complex shape can be formed with high precision.
Compared with traditional forging technology, magnesium alloy semi-solid thixoforming technology has the following advantages:
High-precision forming: The magnesium alloy in the semi-solid state has good fluidity, and can fill the fine structure of the mold to achieve high-precision forming.
Reduce defects: In the semi-solid forming process, the internal defects such as pores and cracks of the material are effectively reduced, and the quality of the forging is improved.
Energy saving and environmental protection: semi-solid thixforming technology has low processing temperature, less energy consumption, and does not need to use harmful lubricants and coolants, which meets the production requirements of green environmental protection.
The semi-solid thixoforming technology of magnesium alloy has been widely used in forging production, especially for products requiring complex shape and high quality. For example, the engine bracket and body structure in automobile parts can be lightweight and meet the strength and stiffness requirements through magnesium alloy semi-solid thixoforming technology. In addition, the technology can also be applied to the production of forgings in the aerospace field, such as aircraft engine parts, fuselage structural parts, etc., which is of great significance for reducing weight and improving flight performance.
With the continuous improvement of product quality and performance requirements in manufacturing industry, semi-solid thixoforming technology of magnesium alloy will play a greater role in forging production. In the future, the technology is expected to make further breakthroughs in the following aspects:
Process optimization: By deeply studying the deformation behavior and microstructure evolution mechanism of magnesium alloy in semi-solid state, the forming process parameters can be further optimized to improve production efficiency and product quality.
Material development: Developing new magnesium alloy materials for semi-solid thixoforming technology to meet the needs of a wider range of applications.
Intelligent production: Combined with advanced technologies such as artificial intelligence and big data, intelligent production of magnesium alloy semi-solid thixoforming technology can be realized to improve the automation level and production efficiency of the production line.
In short, the semi-solid thixoforming technology of magnesium alloy, as a forming technology with great potential, will inject new vitality into the high-quality production of forgings. By continuously optimizing processes, developing new materials and promoting intelligent production, we believe that this technology will play an important role in the future development of manufacturing.
