Abstract
Observation of the growth of recrystallized grains in a strained aluminum sheet was made by the method of X-ray section topograph in order to get the correlation between the structure of the deformed matrix and growth characteristics of recrystallized grains. The recrystallized grain showed marked growth anisotropy when it was related to the deformed crystal with the preferred growth orientation relationship, 40° rotation about the ⟨111⟩ direction, in fcc metal. The deformed matrix appeared to be in the form of lamellae parallel to the slip plane normal, differing in the orientation with a rotation about slip planes. The growth anisotropy was such that the directions of preferred growth were parallel to the slip planes, the normal of which was the rotation axis of slip lamellae and also the rotation axis which represents the orientation relationship between the deformed matrix and the recrystallized grain. The anisotropy was discussed to arise from the inhomogeneous arrangement of dislocations in the deformed matrix.
