hysteresis properties of ring-shaped magnetic cores made by selective laser melting (SLM) from iron powder. The dependence of the magnetic properties of the obtained samples on the parameters of additive manufacturing (speed and direction of the laser beam) and on subsequent heat treatment was investigated. It was found that reducing the speed of the laser beam spot movement along the build surface, selecting the direction of the laser beam spot movement along the axis perpendicular to the squeegee, and performing heat treatment leads to an increase in magnetic induction and magnetic permeability and a decrease in specific magnetic losses. This is due to the fact that during annealing, internal mechanical stresses are removed, the gradient of which hinders the movement of domainboundaries during remagnetization. A comparison of the magnetic properties of printed samples and samples made by pressing from the same powder was carried out. It was shown that the pressed samples are inferior to the samples made by SLM in terms of magnetic induction and permeability.</p></abstract><trans-abstract xml:lang="ru"><p>Работа посвящена изучению магнитных гистерезисных свойств кольцевых магнитопроводов, изготовленных методом селективного лазерного сплавления (СЛС) из порошка железа. Проведено исследование зависимости магнитных свойств полученных образцов от параметров аддитивного производства (скорость и направление движения лазерного пучка), а также от проведения последующей термической обработки. Установлено, что снижение скорости движения пятна лазерного пучка по поверхности построения, выбор направления движения пятна лазерного пучка вдоль оси, перпендикулярной ракелю, а также проведение термической обработки ведет к росту магнитной индукции и магнитной проницаемости и снижению мощности удельных магнитных потерь. Это обусловлено тем, что в процессе отжига происходит снятие внутренних механических напряжений, градиент которых затрудняет движение доменных границ при перемагничивании. Проведено сравнение магнитных свойств напечатанных образцов и образцов, изготовленными прессованием из того же порошка. Показано, что прессованные образцы уступают образцам, изготовленных методом СЛС, по значениям магнитной индукции и проницаемости.</p></trans-abstract><kwd-group xml:lang="en"><kwd>selective laser melting</kwd><kwd>internal stresses</kwd><kwd>soft magnetic materials</kwd><kwd>functional materials</kwd><kwd>additive technologies</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>селективное лазерное сплавление</kwd><kwd>внутренние напряжения</kwd><kwd>магнитомягкие мате- риалы</kwd><kwd>функциональные материалы</kwd><kwd>аддитивные технологии</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Минобрнауки РФ</institution></institution-wrap></funding-source><award-id>FEUZ-2024-0060</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>ГОСТ Р 57558–2017.
