appropriate materials to be used as biodegradable metals to produce new-generation medical implants. Magnesium can decompose in the human body during the healing process. If dissolution is controlled, there is no need in additional operation for implant removal after healing completion. Particularly, Mg-Zn-Ca alloys are considered the most appropriate biodegradable metal implants due to their biocompatibility. In the Mg-Zn-Ca alloys, the addition of Zn and Ca as alloying elements can improve the mechanical properties and increase the corrosion resistance compared to pure Mg without affecting biocompatibility. The work covers the study of the structure and mechanical properties of the magnesium Mg-1%Zn-0.2%Ca alloy after severe plastic deformation (SPD). The research of the structure was carried out using scanning and transmission electron microscopy. The study of mechanical properties was carried out by measuring microhardness and tension tests. The study shows that applying the equal channel angular pressing (ECAP) method and additional treatment with the severe plastic deformation (SPD) method to the Mg–1%Zn–0.2%Ca alloy leads to the formation of the ultra-fine grain (UFG) structure with the average grain size of less than 1 micron. The authors identified that, as a result of strong refinement of the magnesium alloy grain structure, the ultimate strength increases twice up to 283 MPa compared to the homogenized state, when the ultimate strength is 125 MPa. At the same time, in the UFG state, the plasticity significantly decreases up to 3 %.</p></abstract><trans-abstract xml:lang="ru"><p>Известно, что сплавы на основе магния являются подходящими материалами для использования в качестве биоразлагаемых металлов для изготовления медицинских имплантатов нового поколения. Магний может растворяться в человеческом организме в процессе заживления. Если растворение контролируется, то после завершения заживления не требуется дополнительная операция по удалению имплантата. В частности, сплавы системы Mg–Zn–Ca считаются наиболее подходящими для биоразлагаемых металлических имплантатов вследствие их биосовместимости. В сплавах Mg–Zn–Ca добавление Zn и Ca в качестве легирующих элементов может улучшить механические свойства и повысить коррозионную стойкость по сравнению с чистым Mg без ущерба для биосовместимости. Работа посвящена исследованию структуры и механических свойств магниевого сплава Mg–1%Zn–0,2%Ca, подвергнутого интенсивной пластической деформации (ИПД). Исследования структуры проведены с применением растровой и просвечивающей электронной микроскопии. Исследования механических свойств выполнены методами измерения микротвердости и испытаний на растяжение. Показано, что применение метода равноканального углового прессования (РКУП) и дополнительной обработки методом интенсивной пластической деформации (ИПДК) к сплаву Mg–1%Zn–0,2%Ca ведет к формированию ультрамелкозернистой (УМЗ) структуры со средним размером зерна менее 1 мкм. Обнаружено, что в результате сильного измельчения зеренной структуры магниевого сплава происходит значительное повышение предела прочности более чем в 2 раза до 283 МПа по сравнению с гомогенизированным состоянием, в котором наблюдался предел прочности 125 МПа. При этом одновременно в УМЗ состоянии наблюдается существенное снижение пластичности до 3 %.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Mg–1%Zn–0.2%Ca</kwd><kwd>ECAP</kwd><kwd>SPD</kwd><kwd>UFG structure</kwd><kwd>mechanical properties</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Mg–1%Zn–0,2%Ca</kwd><kwd>РКУП</kwd><kwd>ИПДК</kwd><kwd>УМЗ структура</kwd><kwd>механические свойства</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was supported by the Russian Science Foundation No. 20-63-47027.
