АНАЛІЗ ВЛАСТИВОСТЕЙ ТА ОСОБЛИВОСТЕЙ ВИСОКОМІЦНИХ ДЕФОРМОВАНИХ АЛЮМІНІЄВИХ СПЛАВІВ СИСТЕМ Al–Li, Al–Cu–Mn, ЩО ЗАСТОСОВУЮТЬСЯ В АЕРОКОСМІЧНІЙ ГАЛУЗІ ПРИ ВИГОТОВЛЕННІ ЗВАРНИХ КОНСТРУКЦІЙ (Огляд).

The paper presents the main directions of development in the field of promising aluminium alloys. New generation alloys with improved chemical composition, technologies of production and heat treatment of semi-finished products are considered. The question of the relationship between the structure of the alloys and their operational properties, the influence of heat treatment modes and alloying on mechanical properties and weldability of aluminium alloys in order to obtain the specified predicted operational properties is highlighted. The results of the use of aluminium alloys in aviation and space technology are described. A review of industrial deformable alloys of Al-Li and Al-Cu-Mn system, and comparative characteristics of weldability of various promising aluminium alloys (1460, V-1469, 1201 and their analogues 2090, 2195, 2219) is conducted. 30 Ref., 1 Tabl.
