新材料的开发,给以航空、航天、能源、医药为主的各个尖端领域带来很多重大的技术成就。特别是在铁、镍、钴、钛、锆、镁等合金材料领域中,人们已不仅要求其具有高强度和高韧性,还要求其有很强的耐热、耐腐蚀、耐放射线损伤等性能,从而进一步提高在极限使用环境下的性能并大幅度延长机械寿命。为此,目前欧美各国,均竞相开发多功能新合金。现在所使用的合金材料中,一般含有5—10种左右
The development of new materials has brought many major technological achievements to all the cutting-edge areas such as aviation, aerospace, energy and medicine. Especially in the fields of iron, nickel, cobalt, titanium, zirconium, magnesium and other alloy materials, people have not only required its high strength and high toughness, but also required it to have strong heat resistance, corrosion resistance and radiation damage resistance , Thereby further improving the performance under extreme conditions and greatly extend the mechanical life. To this end, the current European and American countries are competing to develop multi-functional new alloy. Now used alloy materials, generally contain about 5-10 kinds
