Замена традиционных конструкционных материалов на МКМ позволит производителям перейти на качественно более высокий технический уровень. Подбор состава, изменение соотношения исходных компонентов и применение различных методов изготовления МКМ позволяют направленно регулировать прочность, жесткость, диапазон рабочих температур и другие физико-механические характеристики материала. Существуют две наиболее распространенные технологии получения дисперсно-армированных МКМ на основе алюминиевых сплавов – жидкофазная и порошковая. Первая предполагает размешивание армирующего компонента в расплаве матричного сплава с последующей кристаллизацией, которая обеспечивает распределение и фиксацию армирующих частиц в объеме матрицы, а вторая представляет собой совместную обработку порошков исходных компонентов в высокоэнергетических мельницах с последующим объединением полученных композиционных гранул методами обработки давлением. Основной целью деформационно-термической обработки является получение заготовок с формой, максимально приближенной к геометрии конечных изделий, а также изменение структуры деформируемого материала, приводящее к повышению уровня прочностных свойств. В работе с использованием порошковой технологии были изготовлены образцы монолитного композиционного материала, исследована их структура и проведены испытания с целью определения плотности и прочностных характеристик МКМ при комнатной температуре. В результате получены дисперсно-армированные МКМ на основе алюминиевого сплава с однородной структурой, плотностью более 99,0 % от теоретической и повышенными механическими свойствами: σв = 300÷305 МПа и Е = 87÷95 ГПа.</p></abstract><trans-abstract xml:lang="en"><p>The study explored various facets of the structure of dispersed-reinforced aluminum alloy-based metal composite material (MCM) under different modes of thermomechanical treatment. Replacing traditional structural materials with MCM provides manufacturers with an opportunity to achieve higher levels of engineering superiority. The ability to choose composition, modify primary component ratios, and employ a range of MCM manufacturing techniques allows for precise tuning of the material's strength, rigidity, temperature range, and other physical and mechanical properties. Two prevalent technologies for crafting dispersed-reinforced aluminum alloy-based MCM exist: liquid-phase and powder technologies. Liquid-phase methodology entails merging the reinforcing component into the binder alloy's melt, followed by crystallization. This process guarantees the dispersion and fixation of reinforcing particles within the binder volume. In contrast, powder technology involves simultaneous processing of primary component powders in high-energy mills, with subsequent amalgamation of the resultant composite granules via pressure molding. The chief aim of thermomechanical treatment lies in yielding blanks that closely mimic the final product's geometry and reshaping the deformable material's structure to heighten its strength properties. Powder technology was employed to fabricate monolithic composite material samples. Their structures were analyzed, accompanied by tests to ascertain density and strength parameters of the MCM at room temperature. Consequently, dispersed-reinforced aluminum alloy-based MCM possessing a uniform structure, density exceeding 99.0 % of the theoretical value, and elevated mechanical attributes: σu = 300÷305 MPa and E = 87÷95 GPa, were successfully produced.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>металлический композиционный материал (МКМ)</kwd><kwd>алюминиевый сплав</kwd><kwd>деформационно-термическая обработка</kwd><kwd>прессование</kwd><kwd>структура</kwd><kwd>прочностные характеристики</kwd></kwd-group><kwd-group xml:lang="en"><kwd>metal composite material (MCM)</kwd><kwd>aluminum alloy</kwd><kwd>thermomechanical treatment</kwd><kwd>pressing</kwd><kwd>structure</kwd><kwd>strength properties</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">Каблов Е.Н.
