Жаропрочные сплавы на основе алюминидов титана Ti2AlNb и TiAl способны составить конкуренцию жаропрочным никелевым сплавам при температурах эксплуатации до 750 оС за счет низкой плотности. Однако при получении сплавов на основе TiAl и Ti2AlNb традиционными методами возникают проблемы, связанные с их ограниченной технологичностью из-за низких характеристик пластичности, ударной вязкости, особенно при пониженных температурах, а также из-за развития ликвационных процессов. Снятие ряда указанных проблем возможно при синтезе этих сплавов аддитивными методами 3D-печати. Авторы проанализировали имеющиеся в литературе данные об аддитивных методах получения жаропрочных сплавов на основе алюминидов титана Ti₂AlNb и TiAl. Представили классификацию аддитивных технологий получения металлических материалов на основе международного стандарта EN ISO/ASTM 52900–2021. Провели критический анализ технологических возможностей различных аддитивных методов получения жаропрочных сплавов титана, включая перспективные гибридные технологии. Рассмотрели возможности получения комплекса механических свойств за счет формирования заданного структурного состоя ния непосредственно в процессе 3D-печати или в процессе термической постобработки. Сфор мулировали ключевые проблемы и предложили направления совершенствования аддитивных технологий для получения рабочих свойств изделий из сплавов на основе интерметаллидов титана.
