【 摘 要 】

The objective of this paper is to identify the predominant crystallographic relations between deformed state and recrystallized grains during the early stages of recrystallization of the Goss{110} and brass{110} oriented single crystals of Al-1%Mn. The analysis was based on high resolution local orientation measurements in scanning electron microscopy. After annealing the disorientation across the recrystallization front 'defines' the final rotation by angles in the ranges of 35o-50o around axes located near the normals of all four {111} slip planes. Although the rotation axes approach the normal vector of the active slip planes during deformation, they only rarely coincide with the exact location of thedirection. For both initial orientations, preferred grain growth occurred along the {111} planes, the most active during strain.
