Systematic studies were carried out on the formation of recrystallized texture of 3% Si-Fe single crystals with pre-selected orientation which were cold rolled to a range from 6 to 95%. Change of the annealing texture was successively examined by using the X-ray pole figure method in relation to the metallographic microstructure.
The recrystallization rate was dependent greatly on the type of the rolled texture and was the higher, the rolling pressure and Vickers hardness the crystal exhibited. The primary texture was composed of one or more components which were characteristic of the type of the end orientations, (000)(001), (111)‹211›, and (112)‹110›, of the rolled texture. In the rolled crystal with multiple components, every region of each component was always occupied only by the corresponding components of the primary texture even if one component of the rolled texture was markedly different from the others in the recrystallization rate.
Some attempts were made at determining the orientation relationship between the newly formed primaries and the rolled matrix consumed by the primaries. Orientation of each primary was crystallographically related to the matrix, even if it appeared to be randomly distributed at first sight. However, the relationship was relationship was not describable definitely by a simple relation.
