Microscale texture of hot deformed 3%Si-steel and statically recrystallized orientations
Recovered and recrystallized crystal orientations of a coarse gained 3%Si-steel hot rolled at 1280degreesC were examined. Deformed samples exhibited a recovered structure comprised of subgrains. It was possible with ECP and EBSD to map the orientations of the subgrains, which were the minimum orientation unit in the present case. Statically recrystallized grains emerged along the original grain boundaries during holding at the rolling temperature for 6.5s. Orientations of the subgrains were observed to continuously rotate near the original grain boundaries of the deformed sample before static recrystallization. On the contrary, there was no recrystallization observed on transition bands in grain interior, probably because of the absence of continuous orientation change near the transition bands.
