It is widely known that copper and its alloys, e.g., Brass, form different rolling textures. This is due to the difference of the plastic deformation mechanisms for pure Cu and its alloys. In turn, detailed study for the texture formation can reveal their deformation mechanisms. In this study, the numerical texture formation simulation is carried out by using visco–plastic self–consistent model. The copper–type texture is reproduced by considering {111} <110> slip and plain strain compression. The consideration of latent hardening, assuming the effect of decomposition of dislocation, realizes more decent prediction for pure copper but not for the alloys. The alloy–type texture with high orientation density at brass orientation is closely reproduced by considering the deformation twinning. However, the predominantly twin reorientation scheme cannot precisely predict the texture. This is due to the assumption that a single orientation reorients to a single twinning orientation, which is not realistic in face–centered cubic metals.
