Определены условия МА реакционных смесей Ti + C в шаровой мельнице. Увеличение массы размольных тел включает механизм МА. Показано, что наибольший эффект от МА получали при двухстадийной подготовке смесей: сначала отдельно активировали титановый порошок, затем осуществляли совместное смешение компонентов, в ходе которого происходило не только их перемешивание, но и активация порошка сажи. Установлено, что на характеристики горения оказывает влияние активация не только титана, но и сажи. После МА обоих компонентов на прессованных образцах обнаружен аномальный рост скорости горения (более 100 см/с). При насыпной плотности влияние МА на процесс горения смесей отсутствовало, поскольку в этом случае скорость горения всех смесей находилась в интервале 1,5–2,5 см/с. Выявлено, что МА реагентов для прессованных образцов приводит к повышению температуры горения, увеличению относительной плотности консолидированного тугоплавкого продукта до 93–95 % и уменьшению среднего размера зерен TiC. Снижение остаточной пористости консолидированного TiC обусловлено ростом температуры горячего прессования и пластичности продукта, синтезированного при горении реакционной смеси после МА. Основная причина – увеличение скорости экзотермического взаимодействия. Показано, что МА при смешении реагентов позволяет управлять параметрами горения, микроструктурой консолидированных продуктов и открывает новые возможности для получения методом СВС-прессования тугоплавких материалов с уникальными структурой и свойствами.</p></abstract><trans-abstract xml:lang="en"><p>The paper studies the effect of mechanical activation (MA) modes when stirring a stoichiometric mixture of titanium and soot powders in a ball mill on the properties of mixtures, combustion parameters, relative density, and the microstructure of consolidated titanium carbide samples obtained by SHS. MA conditions for Ti + C reaction mixtures in a ball mill were determined. An increase in the mass of grinding bodies activates the MA mechanism. It was shown that the greatest effect from MA was obtained with a two-stage preparation of mixtures: firstly, the titanium powder was activated separately, then the components were mixed together, and this process included not only their mixing, but also soot powder activation. It was found that combustion behavior is affected by the activation of not only titanium, but also soot. After MA of both components, an anomalous increase in the burning rate (more than 100 cm/s) was found on pressed samples. At the bulk density, there was no effect of MA on the mixture combustion process, since in this case the burning rate of all mixtures was in the range of 1.5–2.5 cm/s. It was revealed that MA of reagents for pressed samples leads to an increase in the combustion temperature, an increase in the relative density of the consolidated refractory product to 93–95 %, and a decrease in the average size of TiC grains. A decrease in the residual porosity of consolidated TiC is due to an increase in the hot pressing temperature and plasticity of the product synthesized during the reaction mixture combustion after MA. The main reason is an increase in the exothermic interaction rate. It was shown that MA when mixing reagents makes it possible to control combustion parameters, the microstructure of consolidated products and opens up new opportunities for obtaining refractory materials featuring a unique structure and properties by SHS pressing.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>механическая активация</kwd><kwd>шаровая мельница</kwd><kwd>СВС-прессование</kwd><kwd>скорость и температура горения</kwd><kwd>тугоплавкое соединение</kwd><kwd>консолидированный TiC</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mechanical activation</kwd><kwd>ball mill</kwd><kwd>SHS pressing</kwd><kwd>burning rate and temperature</kwd><kwd>refractory compound</kwd><kwd>consolidated TiC</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">Кипарисов С.С., Левинский Ю.В., Петров А.П.
