Abstract A complete set of f.c.c. rolling texture predictions, obtained with the use of a relaxed constraint model, is presented in this paper. The whole spectrum of textures between the copper and brass types can be found if some components of reaction stresses (between grains and the matrix) are relaxed. The best prediction of the copper type texture is found if ϵ 13 is a free parameter and the other components of grain deformation tensor are controlled by reaction stresses. The best prediction of the brass type texture is obtained if ϵ 12 , ϵ 13 and ϵ 23 are free parameters. However, a decisive factor for the texture transition from the copper to the brass type is the relaxation of the ϵ 12 component. We present for all the considered cases the orientation distribution functions (O.D.F.) and also the pole figures for some selected cases. Nous présentons pour tous les cas les fonctions de distribution d'orientations cristallines ainsi que dans certains cas — les figures de pǒles.
