The evolution of the Goss texture in silicon steel
- Seoul National Univ. (Korea, Republic of)
The Goss orientation, {l_brace}110{r_brace}<001>, in about 3% silicon steel has been the subject of speculation from the scientific and technological points of view. The Goss texture, which is not stable with respect to plane strain deformation, rotates toward the {l_brace}111{r_brace}<112> orientation. The Relaxed Constraints (RC) Taylor model, in which shear strains parallel to the rolling direction may occur, causes the formation of the {l_brace}111{r_brace}<112> orientation. The {l_brace}111{r_brace}<112> rolling component is known to lead to the Goss orientation after recrystallization. Raabe and Luecke found that the orientation intensity of the Goss component in the recrystallization texture increased with increasing orientation intensity of the {l_brace}111{r_brace}<112> component in the rolling texture. The above results can explain the structure memory mentioned in an article by Inokuti et al. Inokuti et al. found that the nucleation of {l_brace}110{r_brace}<001> secondary grains takes place in the vicinity of the steel surface zone. The nuclei for secondary grains were found to be the large primary recrystallized grains of near {l_brace}110{r_brace}<001> orientation which were formed by coalescence of several subgrains. They called the nucleation of the Goss orientation structure memory because the nucleation site was thought to be the site of the original Goss orientation formed during hot rolling. The purpose of this work is to discuss the texture transformation from {l_brace}111{r_brace}<112> to {l_brace}110{r_brace}<001> based on the maximum energy release theory.
