ureteral stents are unable to eliminate inflammation, exhibit low strength, and require a second surgery for removal. Metallic bioresorbable stents can reduce the burden on the patient’s body and eliminate additional operations for product removal. <bold>Aim.</bold> To produce a new biocompatible Zn-1 %Cu-1 %Mn alloy and, using equal-channel angular pressing at elevated temperature, to develop an improved set of mechanical properties for potential application as a material for ureteral stents. <bold>Methods.</bold> The Zn-1 %Cu1 %Mn alloy was subjected to equal-channel angular pressing at 200 °C (8 passes, route Bc). The microstructure and elemental composition were studied using transmission electron microscopy with energy-dispersive analysis. Mechanical properties were evaluated under uniaxial tension (strain rate of 10<sup>–3</sup> с<sup>–1</sup>, at least 3 samples per each condition), Vickers microindentation with construction of hardness distribution maps, and fractographic analysis of fracture surfaces using a scanning electron microscope. <bold>Results.</bold> By indexing diffraction patterns, it was established that the deformation processing promotes the precipitation of MnZn<sub>13</sub> phase particles, which may have a strengthening effect. Fractographic analysis of fractured samples after tension showed a change in the fracture character from brittle to ductile with deep dimples. Carrying out equal-channel angular pressing (ECAP) for 8 passes at elevated temperatures allowed increasing the ultimate tensile strength by 2.3 times, the offset yield strength by 3 times, and the percentage elongation by 8 times. The distribution of microhardness values becomes more uniform with an increase in passes from 2 to 8, and the gap between the smallest and largest values decreases. <bold>Conclusions.</bold> It was established that the deformation method (ECAP, 8 passes) for the new biocompatible Zn-1 %Cu-1 %Mn alloy develops an improved set of mechanical properties, which opens up possibilities for its application in medical purposes.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Проблема.</bold> Применяемые в настоящее время для изготовления мочеточниковых стентов материалы не способны устранить воспаление, обладают низкой прочностью и требуют повторной операции по удалению. Металлические биорезорбируемые стенты способны снизить нагрузку на организм пациента и исключить дополнительные операции по извлечению изделия. <bold>Цель.</bold> Цель – получить новый биосовместимый сплав Zn-1 %Cu-1 %Mn и методом равноканального углового прессования при повышенной температуре сформировать его улучшенный комплекс механических свойств для потенциального применения в качестве материала мочеточниковых стентов. <bold>Методы.</bold> Сплав Zn-1 %Cu-1 %Mn подвергали равноканальному угловому прессованию при 200 °C (8 проходов, маршрут Bc). Микроструктуру и элементный состав исследовали методами просвечивающей электронной микроскопии с энергодисперсионным анализом. Механические свойства оценивали при одноосном растяжении (скорость деформации 10<sup>–3</sup> с<sup>–1</sup> , не менее 3 образцов на состояние), микроиндентировании по Виккерсу с построением карт распределения твердости и фрактографическим анализом изломов в растровом электронном микроскопе. <bold>Результаты.</bold> Методом индицирования дифракционных картин установлено, что деформационная обработка способствует выделению частиц фазы MnZn<sub>13</sub>, которые могут оказывать упрочняющий эффект. Фрактографический анализ изломов образцов после растяжения показал изменение характера излома с хрупкого на вязкий с глубокими ямками. Проведение равноканального углового прессования (РКУП) 8 проходов при повышенных температурах позволило повысить предел прочности в 2,3 раза, условный предел текучести в 3 раза, а относительное удлинение в 8 раз. Распределение значений микротвердости с увеличением проходов с 2 до 8 становится более однородным, уменьшается разрыв между наименьшим и наибольшим значениями. <bold>Выводы.</bold> Установлено, что метод деформации (РКУП, 8 проходов) для нового биосовместимого сплава Zn-1 %Cu-1 %Mn формирует улучшенный комплекс механических свойств, что открывает возможности для его применения в медицинских целях.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Zn-Cu-Mn</kwd><kwd>zinc alloys</kwd><kwd>biodegradable metals</kwd><kwd>ureteral stents</kwd><kwd>ECAP</kwd><kwd>equal-channel angular pressing</kwd><kwd>transmission electron microscopy</kwd><kwd>mechanical properties</kwd><kwd>biocompatible alloys</kwd><kwd>biocompatibility</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Zn-Cu-Mn</kwd><kwd>цинковые сплавы</kwd><kwd>биодеградируемые металлы</kwd><kwd>мочеточниковые стенты</kwd><kwd>РКУП</kwd><kwd>равноканальное угловое прессование</kwd><kwd>просвечивающая электронная микроскопия</kwd><kwd>механические свойства</kwd><kwd>биосовместимые сплавы</kwd><kwd>биосовместимость</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The paper was written on the reports of the participants of the XII International School of Physical Materials Science (SPM-2025), Togliatti, September 15–19, 2025.</funding-statement><funding-statement xml:lang="ru">Статья подготовлена по материалам докладов участников XII Международной школы «Физическое материаловедение» (ШФМ-2025), Тольятти, 15–19 сентября 2025 года.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Soria F., de la Cruz J.E., Cepeda M., Serrano Á., Sánchez-Margallo F.M.
