Целью расчетов являлась оптимизация состава и режимов спекания материалов, легированных алюминием, с целью сохранения структуры типа CaCu₅ и обеспечения стабильных гидридообразующих свойств. Были построены сечения фазовых диаграмм при температурах 750–950 ℃ для содержаний 5–20 мас.% Al, а также рассчитаны соответствующие термодинамические параметры, включая энергию Гиббса и энтальпию. Результаты показали, что при содержании 5–10 мас.% Al сохраняется фазовое поле LaNi5 с минимальным количеством вторичных фаз, тогда как при 15–20 мас.% наблюдается формирование интерметаллидов NiAl (ОЦК_B2) и редкоземельных соединений La2Ni7, а также появление жидкой фазы. Проведенный расчет по правилу Шайле показал перераспределение алюминия в жидкой фазе при превышении критического порога – 10 мас.%, что приводит к разрушению исходной структуры и ухудшению водородных характеристик материала. Полученные данные позволяют определить оптимальные условия синтеза и легирования для создания эффективных металлогидридных накопителей водорода нового поколения.</p></abstract><trans-abstract xml:lang="en"><p>This work presents the results of phase equilibrium modeling in the La-Ni-Al system using the Thermo-Calc software. The aim of the calculations was to optimize the composition and sintering parameters of aluminum-alloyed materials to preserve the CaCu5-type structure and ensure stable hydride-forming properties. Phase diagram sections were constructed for temperatures of 750–950 ℃ at aluminum concentrations ranging from 5 to 20 wt.%, and corresponding thermodynamic parameters such as Gibbs free energy and enthalpy were calculated. The results showed that at 5–10 wt.% Al, the LaNi5 phase field is preserved with a minimal amount of secondary phases, while at 15–20 wt.% Al, the formation of NiAl (BCC_B2) intermetallics and rare-earth compounds such as La2Ni7 occurs, along with the appearance of a liquid phase. The Scheil solidification calculation revealed that when the critical aluminum threshold of 10 wt.% is exceeded, aluminum redistributes into the liquid phase, leading to the breakdown of the original structure and degradation of the material’s hydrogen storage properties. The obtained data enable the determination of optimal synthesis and alloying conditions for developing efficient next-generation metal hydride hydrogen storage systems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>материалы для хранения водорода</kwd><kwd>термодинамическое моделирование</kwd><kwd>LaNi5</kwd><kwd>легирование алюминием</kwd><kwd>фазы ОЦК_B2</kwd><kwd>метод CALPHAD</kwd><kwd>Thermo-Calc</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hydrogen storage materials</kwd><kwd>thermodynamic modeling</kwd><kwd>LaNi5</kwd><kwd>aluminum alloying</kwd><kwd>BCC_B2 phases</kwd><kwd>CALPHAD method</kwd><kwd>Thermo-Calc</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена при финансовой поддержке Комитета науки Министерства науки и высшего образования Республики Казахстан в рамках программно-целевого финансирования проекта BR21882200 «Разработка и исследование инновационных технологий, материалов и устройств для производства, хранения водорода и генерации электроэнергии».</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">Умирзаков С.
