Abstract

Note: ƒAE* and ƒÕ** are the deviation angles of rolling plane and direction from the indicated orientation, respectively.

Secondary recrystallization in Fe-3% Si alloy with (110)[001] single-component texture

“…Therefore, for an analysis of the crystallo graphic regularities related to the abnormal grain growth, a material can be used with a sharp single component texture of a primary recrystallization (PR), in which it is possible to observe the initial stages of the SR. In particular, it is well known that the rolling of single crystals of Fe-3% Si alloy with the initial cube on edge (Goss) orientation (110) [001] leads to the formation of two symmetrical octahedral orienta tions {111}〈112〉, and a subsequent recrystallization annealing leads to the formation of an Goss texture with a slight scattering of orientations over all angles [3][4][5][6][7]. This means that the realization of abnormal grain growth in the obtained textured matrix with an Goss texture allows one to study regularities inherent in the SR process.…”

On the Influence of the Annealing Heating Rate on the RecrystallizationTexture of a Deformed Single Crystal(110)[001] of 3% Silicon Iron

“…They appear as a result of neighbouring portions of the single crystal taming in opposite directions about transverse direction (TD) (Hu, 1960;Taoka, Fumbayashi, Takeuchi, 1967). In a single crystal (110)[011 reduced to 70% neighboring bands have the orientations (111) [11] and (111) [ii2].…”

Formation of special misorientations related to transition bands in structure of deformed and annealed single crystal (110)[001] of Fe-3% Si alloy

“…It is well known that the rolling of single crystals with an initial cube on edge (Goss) orientation (110) [001] leads to the formation of two symmetric octahedral orientations {112}〈111〉, and subsequent recrystallization annealing again results in the Goss orientation [1][2][3][4][5]. The structural transformations show that the hereditary mechanism of texture occurs in the material.…”

“…The primary recrystallization (PR) nuclei with the Goss orientation formed in the deformed Fe-3% Si alloy can originate in transition bands, shear bands, and Neumann bands (deformation twins) [1][2][3][4][5][9][10][11]. It has been shown in works [10][11][12] that the formation of the nuclei of Goss grains at twins is accompanied by the appearance and evolution of special misorienta tions (Σ3 → Σ9 and Σ27) in the crystal mesostructure.…”
