Сформированный наплавленный слой толщиной примерно 5 мм имеет каркасную карбидную структуру, которая не разрушается при последующих отпусках и облучении импульсными электронными пучками. Независимо от состояния исследуемого материала в переходной зоне наплавленный слой – подложка формируется мартенситная структура с остаточным аустенитом, расположенным по границам мартенситных пластин в виде отдельных зерен субмикронных размеров. В переходной зоне выявлены наноразмерные частицы карбидной фазы различной морфологии (пластины, глобулы, сферы), расположенные по границам зерен мартенситных кристаллов и аустенитных прослоек. Выявлены карбиды Fe3C, V2C, W2C, CrC, Cr32C2, Cr7C3, MoC, Mo2C, Fe3W3C и Fe6W6C, элементный состав которых определяется сложным составом наплавки. Облучение переходной зоны импульсным электронным пучком приводит к высокоскоростному упрочнению материала с образованием мартенситной структуры преимущественно пластинчатой морфологии. В объеме мартенситных пластин обнаружены частицы карбида хрома CrC.</p></abstract><trans-abstract xml:lang="en"><p>The structural-phase states and defect substructure of transition zone of plasma surfacing with non-current flux-cored wire in the nitrogen medium of R2M9 high-speed steel on the substrate of medium-carbon steel 30HGSA in the initial state, after high-temperature tempering and electron beam treatment were analyzed using scanning and transmission electron microscopy. The formed deposited layer with a thickness of ~5 mm has a frame-type carbide structure, which is not fractured during subsequent tempering and pulsed electron beams irradiation. Regardless of the state of the studied material, a martensitic structure with retained austenite, located along the boundaries of martensite plates and in the form of individual grains of submicron sizes, is formed in the “deposited layer – substrate” transition zone. Nanosized particles of the carbide phase of various morphologies (plates, globules, spheres), located along the grain boundaries of martensite crystals and austenite layers, were identified in the transition zone. Carbides Fe3C, V2C, W2C, CrC, Cr32C2, Cr7C3, MoC, Mo2C, as well as carbides such as Fe3W3C and Fe6W6C, the elemental composition of which is determined by the complex composition of the surfacing, were identified. Irradiation of the transition zone with a pulsed electron beam leads to high-speed hardening of the material with the formation of martensite structure of predominantly lamellar morphology. In the volume of martensite plates, particles of chromium carbide of composition CrC were detected.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наплавленный слой</kwd><kwd>электронная микроскопия</kwd><kwd>переходная зона</kwd><kwd>отпуск</kwd><kwd>импульсный электронный пучок</kwd><kwd>структура</kwd><kwd>свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>deposited layer</kwd><kwd>electron microscopy</kwd><kwd>transition zone</kwd><kwd>tempering</kwd><kwd>pulsed electron beam</kwd><kwd>structure</kwd><kwd>properties</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">Громов В.Е., Чапайкин А.С., Невский С.А.
