Высокоэнтропийные сплавы являются, как правило, однофазными термодинамически стабильными твердыми растворами замещения, преимущественно на основе объемноцентрированной кубической и гранецентрированной кубической кристаллической решеток. Стабилизация твердого раствора при кристаллизации высокоэнтропийного сплава обеспечивается взаимодействием ряда факторов, а именно, высокой энтропией смешения, низкой скоростью диффузии компонентов, малой скоростью роста кристаллитов из расплава. Целью настоящей работы являлось получение новых знаний о структуре и свойствах высокоэнтропийных пленок, синтезированных на металлической подложке при осаждении многоэлементной металлической плазмы в среде аргона. Плазма была сформирована в результате электродугового с плазменным ассистированием независимого распыления катодов титана, алюминия, меди, ниобия, циркония. В результате выполненных исследований выявлен режим осаждения, который позволяет формировать пленки различной толщины близкого к эквиатомному состава. Методами просвечивающей электронной микроскопии установлено, что пленки являются многослойными образованиями, имеют наноразмерную аморфно-кристаллическую структуру. Микротвердость пленок существенным образом зависит от соотношения количества образующих элементов и изменяется в пределах от 12 до 14 ГПа, модуль Юнга – от 230 до 310 ГПа. Кристаллизацию пленок осуществляли путем облучения импульсным электронным пучком. В результате обработки формируется двухфазное состояние. Основной фазой является α-NbZrTiAl с объемноцентрированной кубической кристаллической решеткой с параметром 0,32344 нм; вторая фаза состава CuZr имеет простую кубическую решетку.</p></abstract><trans-abstract xml:lang="en"><p>High-entropy alloys (HEA) are multi-element materials and contain at least five elements of similar concentration. HEA are, as a rule, single- phase thermodynamically stable substitutional solid solutions, mainly based on a body-centered cubic and face-centered cubic crystal lattice. Solid solution stabilization during the crystallization of a high-entropy alloy is provided by the interaction of a number of factors, namely, a high mixing entropy and low diffusion rate of components, and a low growth rate of crystallites from the melt. The purpose of this work was to obtain new knowledge about the structure and properties of high-entropy films synthesized on a metal substrate during deposition of a multi-element metal plasma in argon atmosphere. The plasma was formed as a result of independent plasma-assisted electric arc cathodes of the following metals: Ti, Al, Cu, Nb, Zr sputtering. As a result of the performed studies, the deposition mode was revealed, which allows the formation of films of various thicknesses of close to equiatomic composition. Transmission electron microscopy methods have established that the films are multilayer formations and have nanoscale amorphous-crystalline structure. Microhardness of the films significantly depends on the ratio of number of the forming elements and varies from 12 to 14 GPa, Young’s modulus – from 230 to 310 GPa. Crystallization of the films was carried out by irradiation with a pulsed electron beam. As a result of processing, a two-phase state is formed. The main phase is α-NbZrTiAl with a volume-centered cubic crystal lattice with a parameter of 0.32344 nm; the second phase of CuZr composition has a simple cubic lattice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>высокоэнтропийный сплав</kwd><kwd>пленка-подложка</kwd><kwd>многоэлементная плазма</kwd><kwd>импульсный электронный пучок</kwd><kwd>структура</kwd><kwd>твердость</kwd><kwd>износостойкость</kwd><kwd>коэффициент трения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>high-entropy alloy</kwd><kwd>substrate film</kwd><kwd>multi-element plasma</kwd><kwd>pulsed electron beam</kwd><kwd>structure</kwd><kwd>hardness</kwd><kwd>wear resistance</kwd><kwd>friction coefficient</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке гранта Российского фонда фундаментальных исследований, проект  № 20-58-00006 (анализ структуры пленки ВЭС) и гранта Российского научного фонда, проект № 19-19-00183, https://rscf.ru/project/19-19-00183/ (изготовление пленок ВЭС).
