Выполнено сравнение расчетных данных с экспериментальными. Проанализированы закономерности строения диаграмм состояния систем SiC–B4C–MedB2. Отмечено закономерное снижение концентрации диборида в тройной эвтектике с ростом его температуры плавления. Построены корреляционные зависимости между температурой эвтектики и температурой плавления: tэвт = f(tпл MedB2), энтальпией образования диборида: tэвт = f(ΔHf MedB2). Характер зависимостей близок к наблюдавшимся ранее аналогичным зависимостям в граничных квазибинарных системах SiC–MedB2 и B4C–MedB2. На основании анализа строения и параметров анализируемых систем сделан вывод о перспективности разработки на основе рассмотренных систем широкого спектра конструкционных и функциональных керамических материалов и покрытий, получаемых «свободным» спеканием, а также импульсными методами нагрева и консолидации.</p></abstract><trans-abstract xml:lang="en"><p>Based on the model of regular solutions and experimental data on quasi-binary sections and individual substances, the liquidus surfaces of SiC–B4C–MedB2 quasi-ternary eutectic systems (where boride MedB2 – CrB2, VB2, NbB2, TaB2, TiB2, ZrB2, HfB2, W2B5) are built. The paper provides the comparison of theoretical calculations with experimental data and reviews regularities of SiC–B4C–MedB2 phase diagrams. It is found that there is a regular decrease in diboride concentration in the ternary eutectics with the increase in its melting point. Correlations are established between the eutectic temperature and MedB2 melting point tэвт = f(tпл MedB2), the eutectic temperature and MedB2 formation enthalpy : tэвт = f(ΔHf MedB2). The type of correlations is close to similar correlations observed earlier in SiC–MedB2 and B4C–MedB2 boundary quasi-binary systems. The structure and parameter analysis of the reviewed systems allows for the conclusion on the prospects of developing a wide range of engineering and functional ceramic materials and coatings based on these systems and obtained by pressureless sintering, as well as heating and consolidation pulse methods.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>карбид бора</kwd><kwd>карбид кремния</kwd><kwd>диборид титана</kwd><kwd>диборид хрома</kwd><kwd>эвтектика</kwd><kwd>фазовые равновесия</kwd><kwd>ликвидус</kwd><kwd>тугоплавкие соединения</kwd><kwd>сверхтвердые материалы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>boron carbide</kwd><kwd>silicon carbide</kwd><kwd>titanium diboride</kwd><kwd>chromium diboride</kwd><kwd>eutectics</kwd><kwd>phase equilibrium</kwd><kwd>liquidus</kwd><kwd>refractory compounds</kwd><kwd>superhard materials</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">Thevenot F.
