A Study of Flat Hot-Deformed Semiproducts Аl-Мg-Mn-Sc-Zr Microstructure, Phase Composition, Crystalline Structure and Mechanical Properties

The article investigates the influence of additional thermal treatment of an ingot before deformation on the microstructure, phase composition, crystalline structure, and mechanical properties of flat hot deformed semi-finished products made from Al-Mg-Mn-Sc-Zr aluminum alloy and presents the results obtained. Additional thermal processing of ingots before deformation was carried out in order to increase the level of the mechanical properties of semiproducts. Mechanical properties testing was carried out for both large-sized specimens and for sub-micro volumes of α-aluminum crystalline particles.
