镁锂合金的组织结构及熔炼加工

Microstructure of Mg-Li Alloys and Melting and Rolling Process

镁锂合金因其优异的性能正在受到航空航天及兵器工业的广泛重视,而我国对镁锂合金的研究还很少。镁锂合金生产的难点在于熔铸工艺,只有严格控制工艺条件才能生产出合格的产品。镁锂合金的成分不同,合金中存在的相也不同,需要确定不同的加工工艺。

Recently, more and more attention has been paid to the Mg-Li alloys for its excellent characteristics. However, they are less studied in our country. The difficulty is in the melting and casting process. Accurate controlling is the answer. The content of lithium makes different microstructures that decide different working process.
