Two-Sites Self-Consistent (2-SSC) models have been used for simulation of texture development of two-phase materials (Bolmaro and Lebensohn, 1996; Bolmaro et al., 1997). When both phases are plastically deforming the co-deformation and sharing of spins have to be taken into account via interaction among phases. One-Site Self-Consistent (1-SSC) models are able to consider interaction among each grain and the rest of surrounding grains through a mean field calculated over the “matrix grains”. The next level of complexity, i.e., 2-SSC models, is appropriate to capture some interaction features between phases. In the current paper, starting from well-defined microstructures and textures of Cu–Fe powder composites, the textures obtained after wire-drawing are simulated taking into account codeformation and sharing of rotations. The results are shown agreeing with experimental ones provided that, depending on volume fraction and relative strength of both phases, different ad-hoc strain rate sensitivities are used.
