New models of competitive aviation and space technology cannot be created without contemporary materials. The development of aluminum–lithium alloys was mainly determined by the fact that the addition of lithium to aluminum alloys decreases their density and increases the modulus of elasticity, thereby providing a significant structural weight reduction compared to traditional aluminum alloys. Along with a reduced density, aluminum–lithium alloys have high strength, good corrosion resistance, and good weldability; therefore, they represent a strategically crucial material for aviation and space technology products. This article presents the history of the development of aluminum–lithium alloys and their application.

航空航天技术中铝锂合金的发展及应用前景

没有当代材料,就不可能创造出具有竞争力的航空航天技术新模型。铝锂合金的发展主要取决于以下事实:向铝合金中添加锂会降低其密度并增加弹性模量,从而与传统铝合金相比,可显着降低结构重量。铝锂合金不仅具有降低的密度,而且具有高强度,良好的耐腐蚀性和良好的可焊性。因此,它们代表了航空和航天技术产品的战略关键材料。本文介绍了铝锂合金的发展历史及其应用。
