Effects of segregated sulfur on recrystallization texture and magnetic induction in thin-gauged 3% silicon steel
During final annealing at 1200 C under a high vacuum, changes in recrystallization texture with final annealing time were observed in thin-gauged 3% Si-Fe alloys. In the alloy containing 30 ppm bulk sulfur, the recrystallization texture varied from the {l{underscore}brace}111{r{underscore}brace} to the {l{underscore}brace}001{r{underscore}brace} and finally to the {l{underscore}brace}110{r{underscore}brace} < 001 > Goss texture, resulting in higher magnetic induction than 1.90 T. The trough in magnetic induction, which corresponds to the relatively high surface-segregated sulfur range, is due to the magnetically detrimental effect of those textures, i.e., the {l{underscore}brace}111{r{underscore}brace} and the {l{underscore}brace}011{r{underscore}brace} . In the alloy containing 6 ppm bulk sulfur, the correlation between magnetic induction and surface-segregated sulfur was the same as that in the other alloy. These results clearly indicate that the surface energy induced recrystallization in the thin-gauged 3% Si-Fe alloys is strongly affected by the segregation and the evaporation of sulfur.
