国防科工局局长许达哲近日表示,要结合“国防科技工业2025”和国防科技工业军民融合“十三五”规划的编制,推动我国装备升级。航空发动机具有高度复杂和精密的热力机械性能,长时间处于高温、高强度、高腐蚀的最复杂的恶劣环境中,由此,需要采用一些高强度、耐高温、耐低温,质量轻而又有韧性的材料。稀有金属铟、锗、钨、钼、钒和稀土金属都是制造航空材料的重要金属材料。
Xu Da Zhe, director of the State Bureau of Science and Technology for National Defense recently said that it is necessary to promote the upgrading of China’s equipment in the light of the preparation of the “National Defense Science and Technology Industrial 2025” and the integration of national defense science and technology with industry and civilians in the “13th Five-Year Plan”. Aero-engines have highly complex and sophisticated thermomechanical properties and are subjected to the most complicated and harsh environments of high temperature, high strength and high corrosion over a long period of time, thereby requiring some high strength, high temperature, low temperature, light weight, Tough material. Rare metals Indium, germanium, tungsten, molybdenum, vanadium and rare earth metals are all important metal materials used in the manufacture of aviation materials.
