Возможный набор стабильных ориентировок определяется симметрией деформации. По этой причине стабильные ориентировки связаны определенными кристаллографическими соотношениями, т.е. они могут быть совмещены набором дискретных поворотов. Некоторые повороты из этого набора являются близкими к специальным разориентациям. Текстура ОЦК-металла после большой одноосной деформации (экструзия) исследована ориентационной микроскопией. Специальные границы Σ33а, Σ19а, Σ27а, Σ9, Σ11 наблюдались между некоторыми деформированными зернами. Ориентировки этих зерен соответствовали основным компонентам текстуры деформации. Вероятность возникновения специальной разориентации – специальной границы определенного типа в пределах локальной области была обратно пропорциональной углу поворота вокруг общей оси &lt;110&gt; кристаллической решетки соседствующих зерен.</p></abstract><trans-abstract xml:lang="en"><p>The texture of strongly deformed metal polycrystals was representedby a set of stable grain orientations, which were preserved during the subsequent deformation (texture fi bers). A possible setof stable orientations was determined by the deformation symmetry. For this reason, the stable orientations were bound by specifi c crystallographic relations, i.e. they might be superimposed by a set of discrete rotations. Some rotations in this set were close to special misorientation. Texture of bcc metal after strong uniaxial deformation (extrusion) was investigated by the orientation microscopy (EBSD). Special grain boundaries Σ33a, Σ19a, Σ27a, Σ9, Σ11 were observed between some deformed grains. The orientations of these grains formed the main of deformation texture fi bers. The probability of appearance of special misorientation – of a certain type of special boundaries within a local area was inversely proportional to the angle of rotation about the common axis &lt;110&gt; of the crystal lattice of adjacent grains.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>текстура</kwd><kwd>границы зерен</kwd><kwd>специальные границы</kwd><kwd>специальные разориентации</kwd><kwd>деформация</kwd><kwd>экструзия</kwd><kwd>ориентационная микроскопия.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>texture</kwd><kwd>grain boundaries</kwd><kwd>special grain boundaries</kwd><kwd>special misorientation deformation</kwd><kwd>extrusion</kwd><kwd>orientation microscopy</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">Rusakov G.M., Lobanov M.L., Redikul’tsev A.A., Belyaevskikh A.S.
