ABSTRACT
The creation of new generations of civil and combat aircraft, and leading-edge design solutions for aerospace engineering, requires industrial production development and mastering of new structural materials and new design solutions and processes for their usage in parts. The basic structural materials in civil aircraft are aluminum alloys, but they are also used on a large scale in structures of other aircraft types. In Russia and abroad, research is being carried out toward the development of aluminum alloys to ensure maximum weight efficiency. One of the ways to address this is the development of reduced-density alloy compositions.
