Показано, что композитный сплав 56GM/(W + WC(Ni)) характеризуется градиентной структурой, состоящей из основного слоя стали 56GM, промежуточного слоя 56GM – 56GM/(W + WC(Ni)) и композиционного слоя 56GM/(W + WC(Ni)). Основой слой 56GM характеризуется разнонаправленной игольчатой структурой, что соответствует феррито-мартенситному состоянию. В промежуточном слое 56GM – 56GM/(W + WC(Ni)) игольчатая структура становится менее выраженной. В композиционном слое 56GM/(W + WC(Ni)) формируется равноосная зеренная структура со средним размером зерен 8,59 мкм, по границам которых наблюдаются трещины. Частицы карбида вольфрама WC располагаются преимущественно по границам мелких зерен и в небольшом количестве внутри самих зерен. Методом рентгенофазового анализа установлено, что композит 56GM/(W + WC(Ni)) преимущественно состоит из α-Fe (~80,6 об. %), Ni (~6 об. %), карбидной фазы WC (~10,3 об. %) и незначительной доли γ-Fe (3 об. %). Структура и свойства исходной стали 56GM изменяются не только в области непосредственного добавления легирующего порошка, но и в нижележащих слоях из-за диффузионных процессов и инфильтрации порошка W + WC(Ni) при печати. Значения микротвердости по мере удаления от подложки до композиционного слоя увеличиваются примерно от 3,5 до 6,5 ГПа. Испытания на одноосное растяжение показали максимальные предел прочности и предел текучести в промежуточном слое, которые составили 1100 ‒ 1200 и 835 МПа соответственно.</p></abstract><trans-abstract xml:lang="en"><p>The authors investigated the microstructure and mechanical characteristics of 56GM steel-based composite produced by wire electron-beam additive manufacturing with the addition of W + WC(Ni) powders during printing. The analysis demonstrates that 56GM/(W + WC(Ni)) composite alloy is characterised by a gradient structure consisting of 56GM base layer, 56GM – 56GM/(W + WC(Ni)) intermediate layer and  56GM/(W + WC(Ni)) composite layer. The base layer of 56GM steel is characterized by a multidirectional acicular structure, which corresponds to the ferrite-martensite state. In 56GM – 56GM/(W + WC(Ni)) intermediate layer the acicular structure becomes less pronounced. In 56GM/(W + WC(Ni)) composite layer an equiaxed grain structure is formed, with an average grain size of 8.59 μm, along the boundaries of which cracks are observed. WC particles are located mainly along the boundaries of small grains and in small quantities inside the grains themselves. It was found that 56GM/(W + WC(Ni)) composite is mainly composed of α-Fe (~80.6 vol. %), Ni (~6 vol. %), WC carbide phase (~10.3 vol. %) and γ-Fe (3 vol. %). The structure and properties of initial 56GM steel change both in the area of direct addition of alloying powder and in the underlying layers due to diffusion processes and infiltration of W + WC(Ni). Microhardness values increase from ~3.5 GPa to ~6.5 GPa with distance from the substrate to the composite layer. In uniaxial tensile tests, the ultimate tensile strength and yield strength values reached 1100 – 1200 MPa and 835 MPa in the intermediate layer, respectively.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электронно-лучевое аддитивное производство</kwd><kwd>композит</kwd><kwd>сталь 56GM</kwd><kwd>порошок вольфрама</kwd><kwd>порошок WC(Ni)</kwd><kwd>структура</kwd><kwd>механические свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electron beam additive manufacturing</kwd><kwd>composite</kwd><kwd>56GM steel</kwd><kwd>powder</kwd><kwd>WC(Ni) powder</kwd><kwd>structure</kwd><kwd>mechanical properties</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Института физики прочности и материаловедения Сибирского отделения РАН, тема номер FWRW-2024-0001.
