Abstract
Modern passenger and cargo planes are designed for long-term service of at least thirty years. Stability of the properties of the structural materials used in planes over their entire life is a necessary requirement. The main structural material for a passenger plane is high-strength aluminum alloys, of which are Al−Li alloys the most promising. The present paper is devoted to Al−Li alloys and concerns the nature of the thermal stability, its dependence on various structural factors, and possible ways of stabilizing the properties.
