В работе методами современного физического материаловедения  выполнен анализ элементного и фазового составов, дефектной субструктуры и трибологических свойств поверхностного слоя ВЭС, сформированного в результате облучения импульсным электронным пучком с разной плотностью энергии пучка электронов (10 – 30 Дж/см2) в среде аргона. Показано, что облучение не зависит от плотности энергии пучка электронов и приводит к фрагментации поверхности сеткой микротрещин, что свидетельствует о повышенной хрупкости исследуемого сплава. Отмечена гомогенизация сплава и формирование субмикро- и нанокристаллической структуры. Толщина модифицированного слоя увеличивается от 0,8 до 20 мкм при увеличении плотности энергии пучка электронов от 10 до 30 Дж/см2. Установлена корреляция изменения нанотвердости и модуля упругости с результатами по измерению микротвердости. Коррелированное уменьшение микро- и нанотвердости и модуля Юнга свидетельствует о релаксации внутренних полей напряжений, сформированных при изготовлении сплава. Обработка электронным пучком незначительно влияет на трибологические свойства, но значительно увеличивает прочность и пластичность материала. Наибольшее значение предела прочности на сжатие 2179 МПа получено в сплаве, обработанном электронным пучком с плотностью энергии 30 Дж/см2. Условный предел текучести на сжатие при этом составил 522 МПа, а модуль Юнга 257 ГПа.</p></abstract><trans-abstract xml:lang="en"><p>Volumetric samples of a high-entropy alloy of nonstoichiometric composition were produced by the method of wire-arc additive manufacturing (WAAM). In this work, the methods of modern physical materials science have been used to analyze the elemental and phase compositions, defective substructure and tribological properties of the HEA surface layer formed as a result of irradiation with a pulsed electron beam with different electron beam energy densities (10 – 30 J/cm2) in an argon medium. It is shown that irradiation does not depend on the energy density of the electron beam and leads to fragmentation of the surface by a network of microcracks, which indicates an increased fragility of the alloy under study. The homogenization of the alloy and the formation of a submicro- and nanocrystalline structure are noted. The thickness of the modified layer increases from 0.8 to 20 µm with an increase in the energy density of the electron beam from 10 to 30 J/cm2. The correlation of changes in nanohardness and modulus of elasticity with the results of measuring microhardness has been established. The correlated decrease in micro- and nanohardness and Young’s modulus indicates relaxation of the internal stress fields formed during the manufacture of the alloy. Electron beam treatment has little effect on tribological properties, but significantly increases the strength and ductility of the material. The highest value of the compressive strength of 2179 MPa was obtained in an alloy treated with an electron beam with an energy density of 30 J/cm2. The conditional yield strength for compression was 522 MPa, and the Young’s modulus was 257 GPa.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>высокоэнтропийный сплав</kwd><kwd>электронный пучок</kwd><kwd>облучение</kwd><kwd>структура</kwd><kwd>свойства</kwd><kwd>фазовый состав</kwd></kwd-group><kwd-group xml:lang="en"><kwd>high-entropy alloy</kwd><kwd>electron beam</kwd><kwd>irradiation</kwd><kwd>structure</kwd><kwd>properties</kwd><kwd>phase composition</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Structure and properties of high-entropy alloys.
