Подобран режим спекания, обеспечивающий получение порошковых тел с сохранением исходной формы. Установлено, что применение порошка алюминия марки АСД-1 позволяет получать более плотные брикеты практически во всем исследованном диапазоне температур спекания и обеспечивает лучшую спекаемость прессовок, что объясняется его более чистым химическим составом, дисперсностью и сферической формой зерен. Сплавы состава Al–(2,5÷7,5) ат.% Cr, спеченные при температуре 700 °С, показали наилучшие физико-механические характеристики из всех исследованных образцов.</p></abstract><trans-abstract xml:lang="en"><p>The results of the investigation into the influence of the sintering mode, morphology, and chemical composition of aluminum powders (ASD-1 and PA-1 brands) as well as the content of alloying additive (Cr) on regularities of sintering, structure, and physicomechanical properties of powder bodies of the Al–Cr system with the chromium content of 2,5–20 at.% during liquid-phase sintering at temperatures of 700–900 °C are presented. The sintering mode providing the fabrication of powder bodies with the conservation of the initial form is established. It is found that the application of ASD-1 aluminum powder makes it possible to fabricate more dense briquettes almost overall the studied range of sintering temperatures and provides the better sinterability of compacts, which is explained by its higher chemical purity, dispersity, and spherical shape of grains. Alloy of the composition Al–(2,5÷7,5) at.% Cr sintered at 700°C showed the best physicomechanical characteristics among all studied samples.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>алюминий</kwd><kwd>хром</kwd><kwd>жидкофазное спекание</kwd><kwd>легирующая добавка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aluminum</kwd><kwd>chromium</kwd><kwd>liquid-phase sintering</kwd><kwd>alloying additive</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">German R.M.
