Nickel-base superalloys are indispensable materials for hot-section components of gas turbine engines (GTE); however, traditional manufacturing of geometrically complex parts is highly time- and resource-consuming. The adoption of additive manufacturing (AM), in particular direct laser deposition (DLD), enables high-precision fabrication of free-form components. Nevertheless, most nickel-base superalloys with a high volume fraction of the <bold>γ</bold><bold>′</bold> phase (Ni3Al) are prone to cracking. A promising approach is the development of new alloy compositions specially adapted for AM. <bold>The purpose of this study </bold>is to investigate Investigation of the influence of DLD parameters on cracking behavior, microstructure, and mechanical properties of the previously designed Ni68 and Ni75 alloys based on the ZhS6K superalloy. <bold>Materials and methods.</bold> Thin-walled specimens were produced by DLD with varying laser power, scanning speed, laser spot diameter, and deposition strategy. Cracking susceptibility was evaluated by the specific crack length. Porosity, microstructure, and phase composition were analyzed by optical and scanning electron microscopy. Mechanical properties were assessed by microhardness measurements. <bold>Results and discussion.</bold> A non-linear dependence of the specific crack length on laser power was revealed, with a maximum at 700 W for small spot diameters. The bidirectional deposition strategy was shown to reduce cracking compared with the unidirectional strategy. For the Ni75 alloy, optimum parameters (power 300 W, speed 3 mm/s, spot diameter 1.0–1.5 mm) under the bidirectional strategy were identified, yielding defect-free specimens with a porosity below 0.2%. It was established that the lower carbon content in Ni75 suppresses carbide precipitation, thus reducing the cracking probability. Increasing the laser power from 300 to 1500 W only weakly affects the transverse grain size, but induces a transition from a near-equiaxed morphology to a columnar one with a pronounced <bold>&lt;</bold>100<bold>&gt;</bold> texture; the volume fraction of the strengthening <bold>γ</bold><bold>′</bold> phase remains constant at ~60% for Ni68 and ~41% for Ni75. Microhardness exhibits a weak dependence on the deposition parameters: 390–410 HV for Ni75 and 430–450 HV for Ni68, indicating the predominant contribution of the <bold>γ</bold><bold>′</bold> phase characteristics. The obtained results demonstrate the applicability of the developed alloys for the additive manufacturing of thin-walled high-temperature components.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Жаропрочные никелевые сплавы (ЖНС) являются незаменимыми материалами для горячих узлов газотурбинных двигателей (ГТД), однако традиционные методы производства деталей со сложной геометрией отличаются высокой длительностью и ресурсозатратностью. Применение аддитивных технологий (АТ), в частности прямого лазерного выращивания (ПЛВ), открывает возможность высокоточного изготовления изделий произвольной формы. Однако большинство ЖНС с высокой объемной долей γ′-фазы (Ni3Al) склонны к образованию трещин. Перспективным направлением является разработка новых сплавов, специально адаптированных для АТ. <bold>Цель работы.</bold> Исследование влияния параметров ПЛВ на растрескивание, микроструктуру и механические свойства разработанных ранее на основе ЖС6К сплавов Ni68 и Ni75. <bold>Методы исследования.</bold> Тонкостенные образцы были получены методом ПЛВ, варьируя мощность, скорость сканирования, диаметр лазерного пятна и стратегию выращивания. Склонность к растрескиванию оценивалась по удельной длине трещин. Пористость, микроструктура и фазовый состав были проанализированы с помощью оптической и сканирующей электронной микроскопии. Механические свойства были оценены по измерениям микротвердости. <bold>Результаты и обсуждение.</bold> Выявлена нелинейная зависимость удельной длины трещин от мощности лазера с максимумом при 700 Вт для малых диаметров пятна. Показано, что реверсивная стратегия выращивания снижает трещинообразование по сравнению с однонаправленной. Для сплава Ni75 определены оптимальные режимы (мощность 300 Вт, скорость 3 мм/с, диаметр пятна 1,0…1,5 мм) при реверсивной стратегии, позволяющие получать бездефектные образцы с пористостью менее 0,2 %. Установлено, что более низкое содержание углерода в сплаве Ni75 препятствует выделению карбидов, уменьшая вероятность образования трещин. Увеличение мощности лазера от 300 до 1500 Вт слабо изменяет поперечный размер зерен, но вызывает переход от околоравноосной морфологии к столбчатой с выраженной текстурой &lt;100&gt;; объемная доля упрочняющей γ′-фазы остается постоянной и составляет ~60 % для Ni68 и ~41 % для Ni75. Микротвердость слабо зависит от параметров выращивания: 390…410 HV для Ni75 и 430…450 HV для Ni68, что указывает на определяющий вклад характеристик γ′-фазы. Полученные результаты демонстрируют применимость разработанных сплавов для аддитивного производства тонкостенных деталей высокотемпературного назначения.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Жаропрочные никелевые сплавы</kwd><kwd>Аддитивные технологии</kwd><kwd>Технологические параметры</kwd><kwd>Микроструктура</kwd><kwd>Механические свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Ni-based superalloys</kwd><kwd>additive manufacturing</kwd><kwd>technological parameters</kwd><kwd>microstructure</kwd><kwd>mechanical properties</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при поддержке гранта Российского научного фонда № 23-19-00622-П.</funding-statement><funding-statement xml:lang="en">This research was funded by the Russian Science Foundation, grant no. 23-19-00622-P.</funding-statement><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap></funding-source><award-id>23-19-00622-П</award-id></award-group></funding-group></article-meta><fn-group><fn xml:lang="ru"><p><italic>Финансирование</italic></p> <p>Исследование выполнено при поддержке гранта Российского научного фонда № 23-19-00622-П.</p></fn><fn xml:lang="en"><p><italic>Funding</italic></p> <p>This research was funded by the Russian Science Foundation, grant no. 23-19-00622-P.</p></fn></fn-group></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Reed R.C.
