Установлено, что эффект Баушингера связан с различным вкладом раздвойникования в общую деформацию, а вычисление количественных параметров этого эффекта по критериям напряжения и работы деформации дает близкие результаты. При этом асимметрия поведения магниевых сплавов при растяжении и сжатии одинаковым образом влияет как на напряжение начала пластической деформации (условном пределе текучести), так и на вклад деформации раздвойникования в общую пластическую деформацию. Параметры эффекта Баушингера при сжатии магниевых сплавов близки к нулю, т.е. эффект в этом случае практически не проявляется, а неупругость, ответственная за него, связана с особенностями двойникования именно при растяжении. Сравнение эффекта Баушингера для двух сплавов - промышленного ZK30 и перспективного ZE10 с редкоземельными элементами - во всех случаях говорит в пользу последнего.</p></abstract><trans-abstract xml:lang="en"><p>Features of quantitative evaluation of the Bauschinger effect in magnesium alloys with an asymmetry of deformation behavior regarding tension and compression are considered. It is found that the Bauschinger effect is associated with different contribution of detwinning in total strain in different loading directions. A quantitative evaluation of this effect using stress- and work of deformation approaches renders very close results. The asymmetry of deformation upon tension and compression in magnesium alloys similarly affects both the yield stress and deformation contribution of detwinning in total plastic strain. Parameters of the Bauschinger effect are close to zero when the first loading excursion is in compression, which means this effect is very weak and inelasticity is mostly connected with the twinning process upon tension. The comparison of the Bauschinger effect for commercial ZK60 and promising Mg-based ZE10 (alloyed with rare earths) engineering alloys univocally points to better properties ofthe latter.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Bauschinger effect</kwd><kwd>deformation asymmetry</kwd><kwd>magnesium alloys</kwd><kwd>эффект Баушингера</kwd><kwd>асимметрия деформации</kwd><kwd>магниевые сплавы</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mordike B.
