Показано, что при экструзии через фильеру диаметром 20 мм возникает более неоднородная деформация, чем при экструзии через фильеру 30 мм. Установлено, что при увеличении диаметра фильеры структура материала получается менее дисперсная, но более однородная по размерам. Степень преимущественной ориентации зерен при экструзии через фильеру большего диаметра более высокая. Обнаружено изменение параметра решетки твердого раствора по длине экструдированного стержня, связанного с дефектообразованием в процессе экструзии. Выявлено, что концентрация вакансий больше при экструзии через фильеру меньшего диаметра. Это является следствием более интенсивного протекания процессов динамической рекристаллизации. При переходе к большему диаметру фильеры и более низкой температуре экструзии термоэлектрические свойства материала сохраняются за счет лучшей текстуры.</p></abstract><trans-abstract xml:lang="en"><p>We used mathematical modeling to compare the stress and deformation in a Bi0.4Sb1.6Te3 solid solution base thermoelectric material for extrusion through different diameter dies. The results show that extrusion through a 20 mm diameter die produces a more inhomogeneous deformation compared with extrusion through a 30 mm diameter die. Extrusion through a die of a larger diameter produces a structure that is coarser but has a more homogeneous grain size distribution. The degree of preferential grain orientation is higher for extrusion through a larger diameter die. We found a change in the lattice parameter of the solid solution along the extruded rod, correlating with detect formation during extrusion. The concentration of vacancies is higher for extrusion through a smaller diameter die. This difference between the structures results from a more intense dynamic recrystallization for a smaller diameter die. Increasing the die diameter and lowering the extrusion temperature allow retaining the thermoelectric properties of the material due to a better texture.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>твердый раствор Bi0</kwd><kwd>4Sb1</kwd><kwd>6Te3</kwd><kwd>экструзия</kwd><kwd>текстура</kwd><kwd>термоэлектрическая эффективность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Bi0.4Sb1.6Te3 solid solution</kwd><kwd>extrusion</kwd><kwd>texture</kwd><kwd>thermoelectric efficiency</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Министерства образования и науки РФ (субсидия № RFMEFI57914X0039−14.579.21.0039) и гранта РФФИ (№ 15−02−01794a)</funding-statement><funding-statement xml:lang="en">The work was performed with financial support from the Ministry of Education and Science of the Russian Federation (Subsidy No. RFMEFI57914X0039−14.579.21.0039) and Russian Basic Research Fund Grant (No. 15−02−01794a).</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">Sabo, Ye.
