Установлен оптимальный режим синтеза соединения с содержанием примесной фазы TiN менее 1 %: изотермическая выдержка при температуре 1300 °С в течение 2 ч в среде аргона при давлении 3 атм. Исследовано влияние предварительной механоактивационной обработки порошковой смеси и среды реакционного синтеза на выход фазы Ti2AlN. Показано, что активация приводит к увеличению содержания вторичной фазы TiN. Выявлено, что синтез в вакууме также не позволяет получать монофазный мате- риал Ti2AlN.</p></abstract><trans-abstract xml:lang="en"><p>Ti2AlN MAX-phase was synthesized from the powder mixtures of Ti–AlN using the reactionary sintering method. The optimal synthesis mode for the compound containing less than 1 % of TiN impurity phase was determined: isothermal annealing at 1300 °C for 2 hours in argon at a pressure of 3 atm. The preliminary mechanical activation and the reaction synthesis environment were investigated as the factors that can influence the yield of the Ti2AlN phase. It is shown that the activation increases the level of TiN secondary phase. It was also found that the vacuum synthesis does not enable obtaining of single-phase Ti2AlN.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>МАХ-фаза Ti2AlN</kwd><kwd>реакционный синтез</kwd><kwd>механическая активация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Ti2AlN MAX-phase</kwd><kwd>reaction synthesis</kwd><kwd>mechanical activation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">РФФИ</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Barsoum M.W.
