For rolling and compression deformation of L1{sub 2} polycrystals the texture development, the rotation velocities of the crystals and the Taylor factors are modeled by use of Taylor type models with respect to activation of octahedral and cube slip system. Whereas in the case of rolling, the simultaneously activation of cube and octahedral slip leads to a very sharp maximum of {l_brace}112{r_brace}<111> (C) and to the degradation of {l_brace}110{r_brace}<112> (B), in the case of compression deformation, a new texture component <210> is predicted. When cube and octahedral slip systems are simultaneously active, for both modes of deformation the resulting Taylor factors are similar for all relevant texture components. The rotation velocities of the crystals are weakly affected by the variation of active slip systems. In order to check the compression textures predicted, the results were compared to experimentally detected textures.
