Nucleation of cold rolled FeCo alloy during annealing and its influence onthe formation of recrystallization texture

The orientation distribution of recrystallization grains formed during anne aling, as well as their misorientation relationship to the deformation matr ix in cold rolled FeCo alloy have been investigated. It was found that most of the recrystallization nuclei were located near the boundary area with r ather random orientations, and their misorientation angles to the deformati on matrix were generally very high. However a few nuclei were also observed inside the deformation grains, to which they had very similar orientations . Therefore the misorientation angles between the nuclei and the deformatio n matrix were generally very low. The orientation and the misorientation di stributions of the nuclei have very strong influence on the recrystallizati on process which could result in a very weak recrystallization texture. The corresponding mechanism is discussed.
