Orientation microscopy (EBSD) is used to study structural and textural states through the thickness of pipe steel strips after a controlled thermomechanical treatment. It is shown that texture formation in the form of a selection of components (3 – 7) with a large number of versions of crystallographic orientations, arising with shear phase transformations in accordance with the orientation ratios, suggests presence within the steel structure of elements limiting the number of possible α′-phase orientations. It is proposed that these elements are special boundaries formed during hot rolling close to boundaries RSU Σ3 and Σ11 between deformed austenite grains.

06G2MB 钢带受控热机械处理后的结构和织构状态

定向显微镜 (EBSD) 用于通过受控热机械处理后的管钢带厚度来研究结构和纹理状态。结果表明，以具有大量晶体取向版本的选择成分 (3 – 7) 形式的织构形成，根据取向比随剪切相转变而产生，表明钢结构中存在限制元素可能的 α' 相取向的数量。提出这些元素是在热轧过程中形成的特殊边界，靠近变形奥氏体晶粒之间的边界 RSU Σ3 和 Σ11。
