Formation of recrystallization nuclei was investigated by means of X-ray diffraction and electron microscopy, using aluminum single crystal whose orientation is one of the stable orientation during rolling. Rolling texture is almost the same as the initial orientation but accompanied with orientation spread around [11^^-1] axis normal of cross slip plane of active slip system. On annealing, growth of subgrains with the same orientation as that of the tail of orientation spread were observed by electron microscopy. Recrystallization textures at 623 and 723 K have an orientation relationship which is described by 48° rotation around [11^^-1] axis. Since the other components derived by orientation relationship of preferential growth were not observed, it was suggested that the elongated cells with the same orientation as that of recrystallization texture were effective as the site of recrystallization nuclei. Recrystallization texture at 673 K was ascribed to continuous recrystallization resulting from competition of precipitation and recrystallization.
