Изучены микроструктуры отходов в исходном состоянии, определены типичные размеры основных фаз. Определены основные критерии качества рециклируемых отходов: критерии чистоты (kч), контакта с атмосферой (kа), максимального извлечения металла (ММе). На основании предложенных критериев выполнена градация отходов по эффективности рециклирования. Наименьший суммарный балл присвоен баночным отходам, наибольший – опилкам сплава АК9ч. Эксперименты по синтезированию сплавов Al–Si–Mg (АК7ч), Al–Si–Mn (АК12), Al–Si–Cu–Mg (АК6М2) и Al–Mg–Mn (АМг5) показали, что выход годного варьируется от 82 до 96 %. Минимальный выход годного установлен для сплава АК12, в составе шихты которого преобладали баночные отходы. Химические составы сплавов по содержанию основных легирующих и примесных элементов соответствовали требованиям нормативной документации. При испытаниях механических свойств установлено, что синтезированные сплавы имеют гарантированный запас прочности и пластичности по сравнению с требованиями нормативной документации. На основании металлографических исследований выявлено, что в микроструктуре синтезированных сплавов отсутствуют неметаллические включения и газовая пористость. Немодифицированные и модифицированные образцы из сплава Al–Mg–Mn (АМг5) подвергали прокатке в холодном состоянии в несколько проходов до образования трещин. На образце из немодифицированного сплава трещины появились после 10-го прохода. Образец из модифицированного сплава выдержал 12 проходов до образования трещин. Степень деформации по толщине образца из немодифицированного сплава составила 60,5 %, для модифицированного – 67,2 %.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results of research on the synthesis of Al–Si–Mg (AK7ch), Al–Si–Mn (AK12), Al–Si–Cu–Mg (AK6M2) and Al–Mg–Mn (AMg5) aluminum alloys using dispersed waste: beverage cans (Al–Mn–Mg system), cast alloy sawdust (Al–Si–Mg system), twisted chips of Al–Cu–Mg and Al–Mg–Mn deformable alloys. The waste microstructure was studied in the initial state, and the typical sizes of main phases were determined. The main criteria for the quality of recyclable waste were determined: purity (kp), contact with the atmosphere (ka) and maximum metal recovery (ММе). Based on the proposed criteria, the waste was graded according to recycling efficiency. Can waste received the lowest total score, and AK9ch alloy sawdust had the highest score. Experiments on the synthesis of Al–Si–Mg (AK7ch), Al–Si–Mn (AK12), Al–Si–Cu–Mg (AK6M2) and Al–Mg–Mn (AMg5) alloys demonstrated that the yield varies from 82 to 96 %. The minimum yield was observed for the AK12 alloy with can waste predominating in the charge composition. The chemical compositions of alloys in terms of the content of the main alloying and impurity elements met the regulatory documentation requirements. Mechanical tests showed that synthesized alloys have a guaranteed margin of strength and plasticity in comparison with regulatory documentation requirements. Metallographic studies revealed that the microstructure of synthesized alloys is free from non-metallic inclusions and gas porosity. Non-modified and modified Al–Mg–Mn (AMg5) alloy samples were subjected to cold rolling in several passes until cracking. The non-modified alloy sample began to crack after the 10th pass. The modified alloy sample withstood 12 passes before cracking. The degree of deformation over the sample thickness was 60.5 % for the non-modified alloy, and 67.2 % for the modified alloy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>алюминиевые отходы</kwd><kwd>рециклинг</kwd><kwd>синтезирование сплавов</kwd><kwd>выход годного</kwd><kwd>микроструктура</kwd><kwd>механические свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aluminum waste</kwd><kwd>recycling</kwd><kwd>alloy synthesis</kwd><kwd>yield</kwd><kwd>microstructure</kwd><kwd>mechanical properties</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Минобрнауки РФ в рамках проектной части государственного задания № 0778-2020-0005.</funding-statement><funding-statement xml:lang="en">The research was funded by the Ministry of Education and Science of the Russian Federation as part of the project part of Government Task № 0778-2020-0005.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Nappi C.
