Методом самораспространяющегося высокотемпературного синтеза (СВС), совмещенного с прессованием, впервые получен металло-карбидно-интерметаллидный материал на основе продуктов горения слоевой системы (Ti-Al-Si)/(Ti-C)/Ti. Экзотермический синтез из элементарных порошков осуществляли при давлении 10 МПа, а прессование горячего продукта синтеза - при давлении 100 МПа. В работе продемонстрировано, что в результате СВС-прессования формируется неразъемное соединение слоев «метал/карбид/интерметаллид». Исследованы основные особенности формирования микроструктуры, фазовый состав и прочностные свойства переходных зон на границе между реагирующими СВС-составами Ti-C и Ti-Al-Si и Ti-металлической подложкой. Показано, что в процессе СВС-реакции формируется однородная микроструктура слоев Ti-C и Ti-Al-Si с незначительным содержанием трещин и пор. Толщина переходной зоны между слоями составила не менее 15 мкм. Основной фазой, формирующейся в продукте горения слоя на основе Ti-Al-Si, является, по результатам рентгенофазового анализа, тройная фаза Ti20Al3Si9, содержание которой, посчитанное по методу Ритвельда, составило не менее 87 мас.%. Кроме того, в продукте горения присутствует вторичная фаза Ti3Al в количестве 13 мас.%. Результаты энергодисперсионного анализа показали, что наблюдается диффузия алюминия сквозь слой карбида титана в титановую подложку на глубину ~30 мкм. Значение микротвердости продукта горения слоя на основе Ti-Al-Si составило около 10 ГПа. Прямолинейный характер распространения трещин в синтезированном продукте горения слоя Ti-Al-Si, а также варьирующийся в пределах 5,1-5,7 МПa·м1/2 коэффициент трещиностойкости по Палмквисту говорят о хрупкости материала.

A metal-carbide-intermetallic material based on combustion products of the layer system (Ti-Al-Si)/(Ti-C)/Ti was for the first time obtained with the help of self-propagating high-temperature synthesis (SHS) combined with pressing. Exothermic synthesis from elementary powders was carried out at a pressure of 10 MPa, and pressing of the hot synthesis product was carried out at a pressure of 100 MPa. It has been shown that SHS pressing contributes to the formation of permanent joints of «metal/carbide/intermetallic» layers. The main features of microstructure formation, phase composition, and strength properties of transition zones at the boundary between reacting SHS compositions, Ti-C and Ti-Al-Si and Ti-metal substrate are investigated. It is shown that during SHS reaction, a homogeneous microstructure of Ti-C and Ti-Al-Si layers with an insignificant content of cracks and pores is formed. The thickness of the transition zone between the layers was at least 15 µm. The main phase formed in the combustion product of Ti-Al-Si layer is, according to the results of X-ray phase analysis, triple phase Ti20Al3Si9, the content of which, calculated by the Rietveld method, was at least 87 wt. %. In addition, the combustion product contains a secondary phase of Ti3Al in the amount of 13 wt. %. The energy dispersion analysis revealed that diffusion of aluminium through the titanium carbide layer into the titanium substrate to a depth of approx. 30 µm is observed. Microhardness value of the combustion product of Ti-Al-Si layer was about 10 GPa. The rectilinear nature of crack propagation in the synthesized combustion product of Ti-Al-Si layer, as well as the Palmquist crack resistance coefficient varying within 5.1-5.7 MPa·m1/2, indicate the fragility of the material.
