Спекание сырых брикетов пористостью ~15 % осуществляли при темпера-туре 570–620 °С и времени выдержки от 0,5 до 2,0 ч. Концентрация олова в брикетах увеличивалась с шагом 10 мас.% и достигала 50 мас.%. Установлено, что метод жидкофазного спекания позволяет получать композиты с большим содержанием второй фазы и непрерывной Al-матрицей, способной препятствовать локализации деформации в прослойках мягкой Sn-фазы при внешнем нагружении. Оптимальный режим спекания композитов соответствует температуре 600 °С и выдержке в течение 1 ч. С повышением доли олова связанность алюминиевой матрицы снижается, при этом она остается непрерывной при содержании олова до 50 мас.% (27 об.%). Оценка механических свойств спеченных материалов проводилась путем испытания на сжатие. Прочность полученных спеченных композиционных материалов (КМ) описывается уравнением идеальной смеси: σКМ = σAlfAl + σSnfSn, где σSn – константа, поскольку олово не упрочняется, а значение σAl определяется из кривой сжатия чистого алюминия.</p><sec><title> </title><p> </p></sec><sec><title> </title><p> </p></sec></abstract><trans-abstract xml:lang="en"><p>The structure and mechanical properties of Al–Sn composites produced by vacuum liquid-phase sintering of a mixture of aluminum (ASD-4) and tin (PО2) powders were studied. Sintering of raw briquettes with a porosity of ~15 % was carried out at a temperature of 570–620°C and a holding time of 0,5 to 2,0 hours. The tin concentration in briquettes was increased by step of 10 wt.% and reached 50 wt.%. It was found that the liquid-phase sintering method makes it possible to produce composites with a high second phase content and a continuous Al-matrix capable to prevent localization of deformation in layers of soft Sn-phase under external loading. The optimal composite sintering mode corresponds to a holding time of 1 hour at a temperature of 600 °C. The increase of tin proportion leads to a decrease of the aluminum matrix binding, wherein the matrix remains continuous when the tin content does not exceed 50 wt.% (27 vol.%). Evaluation of mechanical properties of sintered materials was carried out by the compression test. The strength of produced sintered composite materials (CM) is described by an ideal mixture formula: σКМ = σAlfAl + σSnfSn, where σSn is a constant, because tin is not hardened, and σAl value is determined by the compression curve of pure aluminum.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>жидкофазное спекание</kwd><kwd>антифрикционные сплавы Al–Sn</kwd><kwd>структура</kwd><kwd>прочность на сжатие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>liquid-phase sintering</kwd><kwd>Al–Sn antifriction alloys</kwd><kwd>structure</kwd><kwd>compression strength</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">Буше Н.А., Двоскина В.А., Раков К.М., Гуляев А.С.
