Установлено, что литая структура состоит из эвтектических фаз (Al, Zn)4Ca, Al10CaFe2, размером от 5 до 25 мкм, а также неравновесной Т-фазы Al2Mg3Zn3, расположенных по границам дендритных ячеек (Al). Цирконий и скандий образуют с алюминием твердый раствор в результате кристаллизации. После горячей прокатки структура 2 мм-листов состоит из строчечно направленных изолированных интерметалидных частиц и их конгломератов размером до 40 мкм в матрице из (Al). Структура 1 мм-листов характеризуется большей дисперсностью и равномерностью строения. Анализ тонкой структуры деформированных полуфабрикатов с использованием просвечивающий электронной микроскопии показал, что размер наночастиц фазы Al3(Zr, Sc) структурного типа L12 не превышает в сечении 20 нм. В деформированных полуфабрикатах достигнут следующий уровень механических свойств: предел прочности σв ~ 310330 МПа, предел текучести σ0,2 ~ 250280 МПа при относительном удлинении δ ~ 4,57,0 %. Проведены исследования по возможности применения аргонодуговой сварки с использованием в качестве присадочного материала стандартной проволоки СвАМг5. Показано, что новый сплав не проявил склонности к образованию горячих трещин. По результатам рентгеновской томографии величина пористости в сварном шве составила 1,27 об.%. Преобладающий диаметр пор не превышал 0,2 мм. В целом достигнутые структурные и качественные параметры сварных соединений способствуют получению прочности, составляющей 75 % от показателя прочности исходных деформированных полуфабрикатов (листов), что достигается стабилизирующим отжигом при t = 350 °С в течение 3 ч.</p></abstract><trans-abstract xml:lang="en"><p>Process conditions are suggested for manufacturing wrought semi-finished products (2 and 1 mm sheets) from the Al-4.5%Zn-2.5%Mg-2.5%Ca-0.5%Fe-0.2%Zr-0.1%Sc experimental alloy including thermomechanical processing at t = 400450 °С and reduction ratios up to 98 %, as well as softening annealing of the sheet metal at t = 350400 °C for 1—2 hours. It was found that the as-cast structure consists of eutectic phases (Al, Zn)4Ca, Al10CaFe2 5 to 25 gm in size, and a Al2Mg5Zn5 nonequilibrium T-phase located along the boundaries of dendritic cells (Al). Zirconium and scandium form a solid solution with aluminum as a result of solidification. After hot rolling, the structure of 2 mm sheets consists of lineage-oriented discrete intermetallic particles and their conglomerates up to 40 gm in size in the (Al) matrix. The structure of 1 mm sheets features by greater fineness and structure uniformity. The fine structure of deformed semi-finished products was analyzed using transmission electron microscopy (TEM), and this analysis showed that nanoparticles in the Al3(Zr, Sc) phase of the L12 structural type are maximum 20 nm in cross-section. The following level of mechanical properties was achieved in wrought semi-finished products: ultimate strength σв ~ 310330 MPa, yield strength σ0,2 ~ 250280 MPa with relative elongation δ ~ 4.57.0 %. The possibility of TIG welding using standard AMg5 wire as a filler material was studied. It was shown that the new alloy demonstrated no tendency to form hot cracks. According to the results of X-ray tomography, the percentage of porosity in the weld was 1.27 vol.%. The prevalent pore diameter did not exceed 0.2 mm. In general, the resulting structural and qualitative parameters of weld joints contribute to obtaining a strength of 75 % of the strength index of the initial wrought semi-finished products (sheets) achieved by stabilizing annealing at t = 350 °С for 3 hours.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>деформационная обработка</kwd><kwd>аргонодуговая сварка</kwd><kwd>микроструктура</kwd><kwd>механические свойства</kwd><kwd>фрактография</kwd><kwd>компьютерная томография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rolling</kwd><kwd>TIG welding</kwd><kwd>microstructure</kwd><kwd>mechanical properties</kwd><kwd>fractography</kwd><kwd>computer tomography</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дриц А.М., Овчинников В.В.
