Coincidence grain boundary and role of primary recrystallized grain growth on secondary recrystallization texture evolution in Fe3%Si alloy

Influence of Primary Recrystallization Texture through Thickness to Secondary Texture on Grain Oriented Silicon Steel.

“…As N content increased, the grain growth was delayed. Although, Yoshitomi et al 20) reported Tso decreased in case of equilibrium method, in this study (non-equilibrium nitriding method) Tso increased. Figure 12 shows the change of N content and acid soluble Al.…”

“…This is different from the other studies in case of equilibrium method. 20,30,31) To confirm the results, the same experiments were repeated twice. The results did not change.…”

“…This phenomenon has already been reported. [17][18][19][20] B8 decreased drastically with a little addition of N (Nϭ 0.0119%), but if N-content increased more, B8 did not decreased so much. To investigate the cause is the main theme of this study, and is discussed later.…”

“…20,24) The intensities of coincidence orientations to Goss ({110}͗001͘), dispersed Goss ({110}͗229͘) and others orientation in primary textures, I C S9, I C S5 , I C S1 and P CN S1 (the product of I N (the intensity of nucleus orientation N) and I C S1 (the intensity of S1 coincidence orientation)) were calculated.…”

“…It is well known [17][18][19][20] that the sharpness of Goss texture is deteriorated by nitriding the inherent material (ordinary GO). Yoshitomi et al 20) explained the cause by applying the CSL model as follows.…”
