The development of texture in commercial pure copper annealed by laser beam is affected by both the rolling reduction and the initial grain size prior to rolling. For the coarse grained sample I with 70% reduction, the recrystallization texture is nearly random when recrystallization just completes. However, the cube component is evident in the sample II with 92% reduction. For the fine grained sample with 88% reduction, the recrystallization texture consists of the cube component and the cold rolling components at the just full recrystallization state. As grains grow further, the cube component in all the samples increases and the cold rolling components disappear. For the samples heated by laser beam with short time ( < l3.2 ms), no new grains could be observed and the cold rolling components decrease considerably. There is no obvious increase of the cube component. It may be deduced that at the initial stage of recrystallization, there exist a larger number of nuclei of different orientations including the cube and cold rolling components. The further texture development are mainly controlled by the growth competition of all these components.
