Precise prediction of the texture component and simulation of the microstructure evolution facilitate the control and design of the final mechanical and physical properties. Through coupling the finite element simulation and crystal plasticity modelling, the current study introduced a robust technique for predicting the texture component after warm rolling. The simulation was then performed at two temperatures of 300 and 500oC for warm rolling. To calculate the appropriate hardening parameters for the crystal plasticity simulation, the experimental flow curves were obtained from torsion tests at the same temperatures of warm rolling. The presented framework predicted the texture components and associated intensities accurately. This was confirmed followed by comparing the results with the experimental ones. The proposed approach also predicted the flow curves correctly and precisely, as further proved by comparing the simulated flow curve based on the experimental flow curves. Revealing the effect of deformation gradient on the texture evolution, the simulation also showed that the shear components imposed by friction rotated the texture components along the ND direction of the specimen.
