Он состоит в реализации способа осадки с боковым подпором. Заготовка помещается сначала в обойму из пластичного материала, а затем в контейнер. На заготовку воздействуют пуансоном, установленным в контейнер с зазором. Под усилием пресса металл обоймы вытекает в зазор и создает подпор. В результате возрастает уровень сжимающих напряжений, что повышает пластичность магния. Выполнены опыты по деформации магниевых литых образцов, которые показали, что относительное обжатие без разрушения можно увеличить с 12–18 до 60–70 %. Такое повышение пластичности позволяет получать деформированные заготовки из магния без применения операции нагрева. Предусмотрен прием облегченного извлечения заготовок из обойм после окончания деформации. Выявлено, что процесс возможно осуществлять при средних давлениях осадки 820–830 МПа, что приемлемо для современных инструментальных материалов.</p></abstract><trans-abstract xml:lang="en"><p>The study proposes a new method for the cold deformation of cast magnesium. It consists in upsetting using a under lateral pressure. The bar is first placed into a holder made of ductile material, and then into a container. The punch mounted in a container with a gap acts on the blank. Under the press force, the metal contained in the holder flows through the gap and creates a pressure. This increase the level of compressive stresses thus improving magnesium ductility. Deformation tests of cast magnesium specimens were made that showed that the nondestructive reduction of cross-sectional area could be increased from 12–18 to 60–70 %. Such an increase in ductility makes it possible to produce deformed magnesium bars without heating. The method for easier removal of bars from holders after deformation was provided. It was determined that the process could be carried out at moderate upsetting pressures of 820– 830 MPa. This is acceptable for modern tool materials.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>литой магний</kwd><kwd>осадка</kwd><kwd>сжимающие напряжения</kwd><kwd>пресс</kwd><kwd>пластическая деформация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cast magnesium</kwd><kwd>upsetting</kwd><kwd>compressive stresses</kwd><kwd>press</kwd><kwd>plastic deformation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">ФАНО России, Правительство Российской Федерации</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">Powell B.R., Krajewski P.E., Luo A.A.
