“…Another advantage of the alloys of this alloying system is their enhanced workmanship, which allows performing cold bending and punching operations and also avoiding additional re-quenching of assembled structural elements usually made from duralumins in the annealed state because of the low formability of sheets from such alloys as D16chT and 1163T [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

A new series 6xxx Al-Mg-Si alloy is developed with grade V-1381. The influence of the composition and modes of heat treatment on the mechanical and corrosion properties of sheets with a thickness of 1 and 3 mm manufactured at the All-Russian Scientific Research Institute of Aviation Materials (VIAM) is investigated. The average properties of the sheets are as follows: the ultimate tensile strength is σ B = 410 MPa, the yield strength is σ 0.2 = 360 MPa, the elongation is δ = 11.5%, the fatigue crack growth rate is (dl/dN) = 0.59 mm/kcycle at ΔK = 18.6 MPa m 1/2 , the intergranular corrosion is IGC ≤ 0.15 mm, and the exfoliation corrosion (EXFC) is 4 points. It is found out that the sheets are structurally recrystallized, the main strengthening phase is the matrix-coherent β'(Mg 2 Si) phase evenly distributed with a high density across the volume of grains. Another observed process is the heterogeneous origin of the β′ phase on dislocations and dispersoids. The dispersoids observed in the tested specimens have various morphologies. The grain boundaries have emission-free zones 15-20 nm in width. The temperatures and heat values of phase transformations in ingots and sheets are determined, including the measurement of liquidus and solidus points. The sheet weldability is evaluated by automatic argon-arc welding, and critical strain rate V cr of the weld metal during crystallization is determined at which this metal is not covered with cracks. A laser welding mode has been developed to ensure optimal formation of the geometric parameters of the weld.

“…Due to the unique set of properties of aluminum alloy products widely used in various industries, it led to the construction of many factories for the production of building materials, with a significant proportion of semi-finished products accounted for by extruded products. Therefore, all the progress in the field of press production is associated mainly with the development and improvement of technological preparation, providing improved mechanical properties [1,2,3,4].…”

Various types of deformed semi-finished products are prepared from aluminum alloys, such as plates, sheets, tapes, foil, panels, profiles, pipes, rods, forged pieces, wires. These semi-finished products are obtained by processing ingots of continuous casting by pressure - rolling, rolling-off, pressing, forging, stamping or drawing. Pressed semi-finished products are made of aluminum alloys in the majority of cases. The work examines the study of the evolution of the half-finished products microstructure at different stages of their manufacturing in several passes and shows the possibility of obtaining strips of fine-grained structure using pressing in a special device. Also, the research established that, in the material of half-finished product from the AD31 aluminum alloy the smooth fine-grained structure is formed with grains of 6 - 17 μm, which leads to an increase in the strength properties of the alloy and to a preservation of good plasticity.

In the work, on the basis of the analysis of the phase transformations diagram for singlestage aging and temperature-time mechanical and corrosive properties for sheets of alloy 6013, it was established that the maximal values of the strength of the propertiescorrespond toa high tendency to intercrystalline corrosion. In order to improve the complex properties of sheets of alloy 6013 applied two-stage aging. Based on the analysis of the dependencies of the mechanical properties of sheets from alloy 6013 on temperature-time aging regimes, the regime of the first aging stage is selected-170 °С, 1,5 h. Keywords: hardening precipitates, phase transformations at aging, mechanical properties, corrosive properties, temperature-time maps of properties, regime of the first stage of aging. Введение. Сплавы системы Al-Mg-Si-Cu обладают хорошим сочетанием механических свойств, коррозионной стойкости, трещиностойкости, свариваемости и способности к формообразованию, что делает их весьма привлекательными для использования в Bulletin of Science and Technical Development www.vntr.ru № 5 (141), 2019
