“…From the aforementioned results, the warm rolling temperature is a key factor for {001}‐type texture reservation and grain growth in annealed sheets, and the cold‐rolled textures have a substantial influence on the recrystallization textures during annealing . Few in‐grain shear bands occur in sample WR4, and it is hard to provide more recrystallization nucleation sites under the same annealing process; thus, the larger growth space can induce an increase on the final grain size, whereas a large amount of in‐grain shear bands in sample WR1 during cold rolling can contribute to the preservation of small grains in subsequent processes.…”

In this work, the texture evolution, grain boundary character distribution, and magnetic properties of nonoriented Fe–6.9 wt%Si electrical steel are studied. It is found that Fe–6.9 wt%Si steel obtains the higher magnetic inductions based on the heredity of {001} orientation texture during warm rolling, whereas the change in γ‐fiber recrystallization texture is attributed to a significant increase in the frequency of coincidence site lattice grain boundaries after annealing. Meanwhile, the increased recrystallization nuclei in the shear bands lead to the improvement of recrystallization nucleation rate and the decline of grain size because of the accumulation of internal stored energy. Finally, the values of magnetic inductions (B8, B50) and iron losses (P10/50, P10/400) decrease with increasing warm rolling temperatures.

“…Fatayalkadri CITRAWATI, 1,3) Md Zakaria QUADIR 1,2) and Paul Richard MUNROE 1) * (Received on December 12, 2016; accepted on March 7, 2017) In this investigation, a grain oriented silicon steel was annealed from a starting state of its primary recrystallized condition by varying time, temperature and heating rate to elucidate the phenomena that occur during the secondary recrystallization growth of Goss grains. Goss secondary recrystallization occurs in a temperature range from 900 to 1 000°C.…”

“…Compared to some other magnetic materials these alloys are not only economic, but also yield a high magnetic flux under an applied field of 800 A/m (B 800 ). [1][2][3] These properties are related to the presence of Goss grains in the alloy, which have a crystallographic orientation having the < 100 > direction parallel to the rolling direction (RD) and {110} plane parallel to the rolling plane (ND) of the steel sheets. These are then arranged in laminates in the transformer core.…”

“…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.
