The annealing texture of highly rolled Aluminium plate (99.98% purity) consists of the (100)[100] orientation and the retained (123)[112] type orientation. After recrystallization process became complete, the charpening of annealing texture was observed with the passage of annealing time. It is assumed that the cubic orientation may be correspond to an orientation which is gained by about 40° rotation around [111] pole of the (123)[112] type orientation and that is approximately coincident to the pole of a cubic orientation. The retained (123)[112] type orientation may be result from a mechanism of polygonization during annealing, or reorientation by about 45° rotation around two common [111] poles of the (123)[112] type component. We discussed that "oriented nucleation phenomena" may be more important factor to the mechanism of formation of primary recrystallization texture, and moreover "oriented growth " will be affect in a sense of additional factor.
