Выбран состав экзотермической шихты 2Ti + C + + 22,5мас.%Al + 10мас.%TiH2, обеспечивающий получение по технологии СВС пористого каркаса МАХ-фазы Ti2AlC без примесных фаз. Показано, что при пропитке алюминием горячего СВС-каркаса образуются новые фазы: МАХ-фаза (Ti3AlC2), карбид (TiC) и алюминид (Al3Ti) титана. Вместе с тем содержание базовой МАХ-фазы остается высоким, и керамический компонент материала на 76 % состоит из Ti2AlC. При анализе микроструктуры выявлено, что после пропитки и охлаждения композит имеет некоторую остаточную пористость. Выполнены экспериментальные исследования влияния давления пропитки (q = 22, 28 и 35 МПа) на распределение содержания алюминия по высоте и радиусу диаметрального сечения образца. Показано, что неоднородное распределение Al по объему образца обусловлено неоднородными полями давления и температуры и разной уплотняемостью горячих внутренних и более холодных наружных объемов образца. При увеличении давления пропитки степень уплотнения характерных зон выравнивается и неоднородность состава по объему образца уменьшается. При q = 35 МПа разность концентраций алюминия по объему образца не превышает 5 %. По уровню твердости (HB ≈ 150 кг/мм2) СВС-прессованный алюмокерамический каркасный композит на основе МАХ-фазы Ti2AlC соответствует алюминиевым сплавам высокой прочности Al–Zn–Mg–Cu.</p></abstract><trans-abstract xml:lang="en"><p>A one-stage manufacturing technology of aluminum-ceramic skeleton composites by combining the processes of self-propagating hightemperature synthesis (SHS) of a porous skeleton formed by the MAX phase of the Ti2AlC composition and its impregnation by the aluminum melt under the pressure (SHS compaction). A composition of the exothermic charge 2Ti + C + 22,5 wt % Al + 10 wt % TiH2, which provides the formation of a porous skeleton of the Ti2AlC phase without impurity phases by the SHS technology, is selected. It is shown that when impregnating the hot SHS skeleton with aluminum, new phases are formed such as the MAX phase (Ti3AlC2), titanium carbide (TiC), and titanium aluminide (Al3Ti). However, the content of the basic MAX phase remains high, and the ceramic component of the material consists of Ti2AlC by 76 %. When analyzing the microstructure, it is revealed that the composite has certain residual porosity after the impregnation and cooling. The influence of the impregnation pressure (q = 22, 28 and 35 MPa) on the distribution of the aluminum content over the height and radius of the diametral sample section is investigated experimentally. It is shown that the nonuniform Al distribution over the sample bulk is caused by the nonuniform pressure and temperature fields as well as different compactibility of hot inner and colder outer sample parts. The degree of compaction of characteristic zones is leveled as the impregnation pressure increases, and composition inhomogeneity over the sample bulk decreases. The difference of aluminum concentration over the sample bulk at q = 35 MPa does not exceed 5 %. By the hardness level (HB ≈ 150 kg/mm2), the SHS-compacted aluminum-ceramic skeleton composite based on the Ti2AlC MAX phase corresponds to high-strength Al–Zn–Mg–Cu aluminum alloys.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>алюмокерамический композит</kwd><kwd>каркас</kwd><kwd>самораспространяющийся высокотемпературный синтез (СВС)</kwd><kwd>МАХ-фаза</kwd><kwd>пропитка под давлением</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aluminum-ceramic composite</kwd><kwd>skeleton</kwd><kwd>self-propagating high-temperature synthesis (SHS)</kwd><kwd>MAX phase</kwd><kwd>pressure impregnation.</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">Adebisi A.A., Maleque M.A., Rahman M.M.
