Показано, что вовлечение в состав шихты деформированных отходов (электротехнических отходов алюминия и баночных отходов на основе сплава 3104 – для АК9ч; пластин сплава АМг6 – для АМг6л) способствует формированию дисперсной микро- и макроструктуры рабочих сплавов в твердом состоянии. Исследовано влияние модифицирования (лигатура AlSr20 – для АК9ч; лигатура AlTi5 – для АМг6л) на структуру и механические свойства сплавов, полученных по различным вариантам шихты. Эксперименты по влиянию состава шихты на модифицируемость сплавов АК9ч и АМг6л выявили, что структура деформированных отходов частично наследуется рабочими сплавами через жидкое состояние. При близких химических составах меньшими размерами микро- и макроструктуры и повышенными механическими свойствами (предел прочности и относительное удлинение при растяжении) характеризуются сплавы, полученные с использованием повышенной доли деформированных отходов в составе шихты. Установлено, что в таких сплавах превышение определенного количества элемента-модификатора (0,06 % Sr – для сплава АК9ч; 0,04 % Ti – для сплава АМг6л) обуславливает проявление эффекта перемодифицирования. Это выражается вь укрупнении параметров микро- и макроструктуры, а также снижении предела прочности при растяжении. Полученные результаты показывают, что оптимальное количество доли деформированных отходов в составе шихты позволит на практике сократить расход дорогостоящих модифицирующих лигатур с обеспечением гарантированного эффекта от модифицирования.</p></abstract><trans-abstract xml:lang="en"><p>   The paper provides the results of studies into the effect of the charge composition on the structure and mechanical properties of Al–Si–Mg (AK9ch) and Al–Mg (AMg6l) cast aluminum alloys. It was shown that deformed waste included in the charge composition (electrical waste of aluminum and waste of beverage cans based on the 3104 alloy – for AK9ch; AMg6 alloy plates – for AMg6l) contributes to the formation of dispersed micro- and macrostructure of working alloys in the solid state. The effect of modification (AlSr20 master alloy – for AK9ch; AlTi5 master alloy – for AMg6l) on the structure and mechanical properties of alloys obtained with various charge options was studied. Experiments on the effect of the charge composition on the AK9ch and AMg6l modifiability showed that the deformed waste structure is partially inherited by working alloys through the liquid state. With similar chemical compositions, alloys obtained with an increased proportion of deformed waste in the charge composition feature by smaller micro- and macrostructure sizes and improved mechanical properties (tensile strength and tensile elongation). It was found that when a certain amount of the modifier element (0.06 % Sr for the AK9ch alloy; 0.04 % Ti for the AMg6l alloy) is exceeded in these alloys, the over-modification effect appears. This is expressed in enlarged micro- and macrostructure parameters, as well as lowered tensile strength. The results obtained show that the optimal amount of the deformed waste proportion in the charge composition will make it possible to reduce the consumption of expensive modifying master alloys with a guaranteed effect of modification in practice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>алюминиевые сплавы</kwd><kwd>деформированные отходы</kwd><kwd>модифицирование</kwd><kwd>структура</kwd><kwd>механические свойства</kwd><kwd>явление структурной наследственности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aluminum alloys</kwd><kwd>deformed waste</kwd><kwd>modification</kwd><kwd>structure</kwd><kwd>mechanical properties</kwd><kwd>structural heredity phenomenon</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">Murty B.
