The 〈111〉 rotation recrystallization mechanism, that is the slip band intersection model, presents that a 〈111〉 rotation recrystallization nucleus is formed in an intersection part of two kinds of slip bands. The nucleus is obtained by the rotation of the deformed matrix around 〈111〉 axis normal to the common cross slip plane of these slip systems. Eight kinds of nuclei are composed of four 〈111〉 axes with clockwise and counterclockwise rotations. For these formations in tensile deformation, the operation of slip bands with compressive strain plays an important role. So the operation of twenty-four slip systems including plus and minus directions should be estimated. In tensile deformation, the recrystallization nuclei of 〈001〉, 〈112〉, 〈111〉, and Schmid factor m=0.5 with kink bands in aluminum single crystals have been estimated and compared with the experimental results, and good relations have been found between them in terms of the selection of kinds of nuclei and their frequency.
