“…f(Recalculated {111}<112>) = 0.46 × fGoss + 0.32 × frotated-Cube + x × frandom (7) The contribution of the random part (x) cannot be calculated directly from the random initial texture in Fig. 9 because it contains the Goss and rotated Cube components.…”

“…Many investigations have been focused on the evolution of the Goss texture during the primary and secondary recrystallization of Fe-3%Si [2][3][4][5][6][7][8][9][10][11][12][13], where the origin of this Goss component was related to the {111}<112> texture, which develops after cold rolling. The cold rolling texture itself was linked to the Goss component of the initial texture developed during hot rolling.…”

Plastic deformation of Fe-27%Co alloy at room temperature was investigated. The present alloy, usually delivered with a low-texture component for the magnetic core in rotating machines, develops a rather high intensity of Goss texture after recrystallization, when a suitable manufacturing process is applied. Thanks to this texture and its magnetic properties, this material can replace the grain-oriented Fe-3%Si alloy in electric transformer application. The intensity of the recrystallization Goss component depends directly on the sharpness of the {111}<112> orientation developed during cold rolling. Thus, the origin of this {111}<112> deformation texture has been studied using viscoplastic self-consistent (VPSC) simulations. This model showed that only the {110}<111> slip systems allow to develop the {111}<112> texture. The predominance of this slip system has been effectively identified from slip markings on the deformed sample by EBSD. More, this simulation has shown that a Goss texture at the hot-rolled state favors the {111}<112> development during cold rolling, as observed experimentally.

“…In nearly every stage until box annealing there are crucial factors for the inhibition system which has to restrain normal grain growth and to control secondary recrystallization. The maximal inhibition effect is obtained with a homogeneous distribution of particles having diameter in the range of 50-100 nm [11,12]. On the other hand, it is necessary to provide the presence of {110}<001> oriented grains in the primary recrystallized fine grained matrix [13,14].…”

This work investigates the microstructure and texture evolution in grain-oriented electrotechnical steel with a new inhibition system based on vanadium carbides nano-particles. The novel approach for the preparation of this steel with appropriate final magnetic properties combines not only nanoinhibitors based on the vanadium carbides precipitations but also includes straininduced grain growth mechanism in combination with dynamic continuous annealing during the secondary recrystallization. The experimental grain-oriented steel with proposed new chemical composition was prepared in laboratory conditions. The texture analysis has shown that suggested procedure led the formation of sufficiently strong {110}<001> Goss texture during the short time period of a final annealing process, which is comparable to that obtained in the conventionally treated grain-oriented steels.

“…The metallurgical factors which affect the magnetic properties include the steel composition, microstructure, crystallographic texture, grain size, and internal stress, of which microstructure and texture are important influencing factors [3]. Due to the obvious inheritance of the textures [4] during manufacturing, the hot rolling textures have significant effect [5] on the texture evolution during the following process of grain-oriented silicon steel. The research on the origin and evolution of textures is beneficial for the optimization of texture control in the production processes.…”

The influence of hot deformation temperature on microstructure and texture of CGO silicon steel under the condition of a high deformation rate (100 s-1) was studied by SEM and EBSD techniques. The results indicate that the typical microstructures at room temperature consist of ferrite and pearlite under different hot deformation temperatures. The higher deformation temperature is beneficial to obtain a more uniform recrystallization microstructure and lower pearlite content. Cubic texture{100}001and rotated cubic texture{100}011are dominant texture components in the tested steels, and{111}112texture inγfiber is also strong, the intensity of which is higher than that of{111}110texture. Goss texture{110}001is weak. With the rising of the hot deformation temperature,{100}011texture decreases firstly and then increases at 1100°C. When the hot deformation temperature raises from 800°C to 900°C,{111}112texture shows an increasing trend, while{111}110texture content is stable. When the temperature further increases to 1100°C and 1150°C,{111}112and{111}110textures are slightly weakened.
