ИССЛЕДОВАНИЕ ВЫСОКОЭНТРОПИЙНЫХ СПЛАВОВ И ОБЛАСТЬ ИХ ПРИМЕНЕНИЯ

Представлены современные направления исследований высокоэнтропийных сплавов (ВЭС), включая их фундаментальные аспекты, методы изготовления, упрочнения, а также области их применения. Проанализированы основные механизмы формирования микроструктуры и фазового состава ВЭС, подчеркивается центральная роль высокой конфигурационной энтропии в стабилизации однофазных твердорастворных структур и создании уникальных свойств, превосходящих традиционные сплавы. Систематизированы четыре основных направления исследований: термодинамическое обоснование фазообразования, микроструктурные трансформации, механические и функциональные свойства, а также разработка новых классов сплавов и легирующих концепций. Особое внимание уделено комплексному анализу различных методов производства ВЭС, начиная от традиционных плавочно-литейных технологий (вакуумная индукционная плавка, вакуумно-дуговой переплав, электрошлаковая плавка) и порошковых методов до современных инновационных аддитивных подходов (селективное лазерное сплавление, электроннолучевое плавление, лазерная наплавка). Показано, как различные технологии синтеза обеспечивают контроль над микроструктурой, размером зерен и фазовым распределением. Рассматриваются механизмы упрочнения ВЭС (твердо-растворное и осадочное упрочнение наночастицами), а также создание гетерогенных структур и упрочнение дефектами, что позволяет достигать оптимального сочетания прочности и пластичности. Обозначены основные области практического применения ВЭС — от аэрокосмической и энергетической промышленности до биомедицинского оборудования, защитных покрытий и каталитических применений. Подчеркивается растущее значение ВЭС в экстремальных условиях эксплуатации благодаря их термостабильности и коррозионной устойчивости. В заключительной части определены перспективные направления дальнейших исследований, включая развитие методов масштабирования производства, стандартизации материалов и использования вычислительных моделей для ускоренной разработки новых композиций. Подчеркивается необходимость междисциплинарного подхода, объединяющего передовые технологии производства с фундаментальными исследованиями, что открывает широкие перспективы для успешного внедрения ВЭС в высокотехнологичные сферы современной промышленности.
