Мощность лазерного излучения варьировали от 1200 до 2000 Вт. Было отмечено, что низкая мощность лазера может привести к более высоким скорости охлаждения и дефектности в микроструктуре образцов. Мощность излучения 2000 Вт привела к получению самых высоких механических свойств при растяжении. Было исследовано влияние термической обработки на микроструктуру, твердость и свойства при растяжении. При исследовании образцов после разрушения обнаружено, что в изломах образцов, полученных при мощности 1400 ‒ 1800 Вт, присутствуют дефекты в виде непроплавов и трещин. В изломах образцов, изготовленных при мощности лазера 1200 и 1600 Вт, присутствуют не расплавившиеся частицы порошка. На поверхностях излома всех образцов присутствовали ямки и классическая форма чашечки и конуса, указывающие на вязкий механизм разрушения. Было обнаружено, что термическая обработка может полностью гомогенизировать микроструктуру, привести к относительно однородным, равноосным зернам и увеличить твердость материала. Термическая обработка снижает анизотропию свойств, приводит к повышению уровня свойств на растяжение при разной мощности лазера. Исследование предоставляет первоначальную основу, чтобы помочь конструкторам и специалистам с выбором мощности лазера, а также понимать его воздействие на жаропрочный сплав, влияние на микроструктуру и механические свойства при комнатной температуре</p></abstract><trans-abstract xml:lang="en"><p>The microstructure and tensile mechanical properties of samples made of a heat-resistant nickel-based alloy obtained using the direct energy and material supply (LP-DED) process have been studied. The power of the laser radiation varied from 1200 to 2000 watts. It was noted that low laser power can lead to higher cooling rates and defects in the microstructure of the samples. The radiation power of 2000 W resulted in the highest mechanical properties under tension. The effect of heat treatment on microstructure, hardness and tensile properties was investigated. When examining the samples after destruction, it was found that defects in the form of non‒melts and cracks are present in the fractures of the samples obtained at a power of 1400 - 1800 watts. In the fractures of the samples made at a laser power of 1200 and 1600 W, there are non-molten powder particles. On the fracture surfaces of all samples, pits and the classic shape of a cup and cone were present, indicating a viscous fracture mechanism. It was found that heat treatment can completely homogenize the microstructure, lead to relatively homogeneous, equiaxed grains and increase the hardness of the material. Heat treatment reduces the anisotropy of properties, leads to an increase in the level of tensile properties at different laser power. The study provides an initial basis to help designers and specialists with the choice of laser power, as well as to understand its effect on a heat-resistant alloy, its effect on microstructure and mechanical properties at room temperature.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>процесс прямого подвода энергии и материала</kwd><kwd>сплав ЭП648</kwd><kwd>мощность лазерного излучения</kwd><kwd>механические свойства при растяжении</kwd></kwd-group><kwd-group xml:lang="en"><kwd>direct energy and material supply process</kwd><kwd>EP648 alloy</kwd><kwd>laser radiation power</kwd><kwd>mechanical properties in tension</kwd><kwd>heat treatment</kwd><kwd>microstructure</kwd><kwd>hardness</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Минобрнауки России в рамках реализации комплексного проекта по созданию высокотехнологичного производства по теме «Организация высокотехнологичного производства индустриальных ГТД с интеллектуальной системой конструкторско-технологической подготовки для повышения функциональных характеристик» (Соглашение о предоставлении гранта № 075-11-2021-042 от 24.06.2021 г.)</funding-statement><funding-statement xml:lang="en">The work was carried out with the financial support of the Ministry of Education and Science of Russia within the framework of implementation of the complex project on creation of high-tech production on the theme "Organization of high-tech production of industrial GTD with an intelligent system of design and technological preparation to improve functional characteristics" (Grant Agreement no. 075-11-2021-042 dated 24.06.2021).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kubiak K. et al.
