Abstract: The present investigation described about the relation between grain orientations and recrystallization mechanism during static annealing of pure magnesium. Commercially pure magnesium was subjected to cold rolling to reduce 90% of the thickness. Subsequently rolled samples were subjected to annealing within a range of annealing times starting from 10 s to 3600 s. A strong basal texture was observed in the samples and also the maximum weakening of basal texture was seen during annealing at 300 s. No new orientations were seen during annealing of magnesium. However, the rate of movement of very low angle grain boundary (VLAGB) was the chief controlling step for the formation of the recrystallized grains. The formation of sub-grains from the parent grains was seen during annealing without any relation with the orientation of the grains. However, the rate of formation of sub-grain was faster in the grains whose orientation > 40o from the normal direction (ND) of the sample. There was also seen the reduction in growth rate of orientations/grains with increasing their deviation from ND of the sample.
