Получение высокоэнтропийного сплава CoCrFeNiMn, легированного азотом, методом селективного лазерного сплавления

Представлены результаты исследования возможности получения высокоэнтропийного сплава CoCrFeNiMnNх методом селективного лазерного сплавления. Порошки высокоэнтропийного сплава CoCrFeNiMnNх (с расчетным содержанием азота х 0,1, 0,2 и 0,5 мас.%) получали методом механического легирования с последующей плазменной сфероидизацией. Процесс компактирования сплавов селективным лазерным сплавлением и их механические свойства исследовали при комнатной и криогенной температурах. При снижении температуры механические свойства сплавов с содержанием азота 0,1 и 0,2 мас.% повышаются соответственно: условный предел текучести – на 27,2 и 63,3%, предел прочности – на 30,8 и 52,7%.
