Abstract
With the development of aircraft engineering the number of aluminum-lithium alloys is growing substantially. However, in determining the domain of their application data on the stability of the solid solution and the hardenability should be taken into account. A frequent mistake is the use of an alloy with low stability of the solid solution for preparing thick-walled semifinished products, for example, complexly shaped large forgings. In this case “dark spots” appearing on the surface of massive elements and zones of incomplete hardening in the central part worsen the characteristics of static and cyclic crack resistance. The article is devoted to problems of hardenability of aluminum-lithium alloys.
