Исследованы закономерности формирования из паровой фазы толстых (до 100 мкм) конденсатов высокоэнтропийных сплавов систем CrFeCoNiCu и AlCrFeCoNiCu при электронно-лучевом осаждении. Получены вакуумные конденсаты сплава CrFeCoNiCu при стационарном режиме испарения слитка CrFeCoNiCu, а сплава AlCrFeCoNiCu — путем совместного осаждения паровых потоков сплава CrFeCoNiCu и Al на общую подложку. Установлено, что стационарному режиму испарения слитка CrFeCoNiCu предшествует переходной процесс испарения элементов с переменными соотношениями компонентов, обусловленный различием коэффициентов их активности в ванне расплава. Показано, что температурные границы структурных зон вакуумных конденсатов высокоэнтропийных сплавов смещены относительно границ структурных зон, свойственных чистым металлам и соединениям. Библиогр. 31, табл. 2, рис. 8.
Ключевые слова: высокоэнтропийные сплавы; электронно-лучевое осаждение; вакуумные конденсаты; фазовый состав; структурные зоны; кристаллографическая текстура
