Xinhua News Agency, Beijing, December 15 (Reporter Hu Zhe) As the lightest engineering metal material, magnesium alloy is known as the 'green engineering material in the 21st century'. Because of its unique advantages, it has broad application prospects. Cast magnesium alloys, especially high-strength and heat-resistant rare-earth magnesium alloys, have been widely used in the aerospace field. In recent years, new magnesium alloy processing technologies and innovative applications have emerged all over the world.
A few days ago, at a forum with the theme of 'Focus on Advanced Magnesium Alloy Technology', academicians and experts from various parties talked about the future advanced magnesium alloy technology to promote the transformation and upgrading of precision manufacturing to 'intelligence'.
Ding Wenjiang, an academician of the Chinese Academy of Engineering, believes that the current resources and environment have become the primary issues of sustainable human development. The resources of the shell are becoming increasingly depleted, and magnesium is one of the most abundant light metal elements on the earth, which can be said to be inexhaustible. Therefore, today, when many traditional metal minerals tend to be exhausted, accelerating the development of magnesium materials is essential for maintaining sustainable social development. have important strategic significance.
The transformation and realization of high-end technology is an inescapable topic in all fields of scientific and technological research and development. Zhong Kui, an academician of the Chinese Academy of Engineering, analyzed that the extreme development of the service functions of modern high-end equipment is faced with how to get rid of the disturbance of residual stress to high performance, high precision and high reliability.
In this process, the role of China Aerospace has quietly changed. It is reported that Shanghai Institute of Aerospace Precision Machinery has now mastered the alloy composition formula, smelting and heat treatment process of casting heat-resistant magnesium alloys, and has compiled aerospace industry standards, and the technical level has reached the domestic leading level.
The relevant person in charge of the forum introduced that China Aerospace has the foundation, conditions and advantages of advanced manufacturing industry, has accelerated the pace of construction of process technology innovation platform, played a leading role in the development of process technology, and provided professional manufacturing for the development of the aerospace industry to the greatest extent. surgical traction.
