Current-Technology Aluminum Alloys for Aerospace Applications (Abstract)



Metal Science and Heat Treatment Vol. 43, Nos. 7 – 8, 2001 28th CHERNOV READINGS. MEMORIAL LECTION I. N. Fridlyander Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 8, p. 6, August, 2001. “At the turn of the Third Millennia aluminum alloys remain the chief structural material in aircraft and rockets. I considered this problem circumstantially in the article “Aluminum alloys in aircraft in 1970 – 2000 and 2001 – 2015” published in the journal “Metal Science and Heat Treatment,” No. 1 of 2001, and therefore will not speak of the mechanical and physical properties of these alloys. Today I will present numerous examples of Al – Cu, Al – Cu – Mg, Al – Cu – Li, Al – Mg – Li, Al – Cu – Mg – Li, Al – Si, Al – Mg – Si, and other systems employed in aerospace engineering. Aluminum alloys with various alloying sets can be classified not only according to the combination of their properties but also according to the destination in the aircraft, for example, for airplane wings, fuselages, frames, fittings, and liquid-fuel tanks.” Then the reporter presented a series of photographs of parts produced by domestic and foreign producers of aircraft beginning with small vertical takeoff deck fighters and ending with giant “MRIYA” airplane carriers and space shuttles of the “Buran” type based on various domestic aluminum al- loys. However, the main attention of the reporter was devoted to Al – Li alloys and their successful use in all-welded structures. Stressing the priority of Russia in this field, I. N. Fridlyander spoke about the successful Russian-European cooperation in the production of the A3XX airbus and the Russian-American cooperation in the production of fuel tanks for Delta-type rockets orbiting world-communications satellites. Answering the questions of the listeners I. N. Fridlyander drew an optimistic picture of the use of aluminum alloys in the automobile industry and in railroad, marine, and river transport. In support of his words about successful Russian-American cooperation in the field of creation of Al – Li alloys I. N. Fridlyander suggested that the section devoted to the Chronicle of the 28th Chernov Readings should be concluded with the presentation of the results of a joint research recently performed in Russia (the All-Russia Institute of Aircraft Materials) and in the USA (NASA, the Langley Research Center). Below we present a paper describing the joint work of Russian and American researchers. 0026-0673/01/0708-0297$25.00 © 2001 Plenum Publishing Corporation
