“…The surface texture was even weaker, and next to Cube it showed typical shear deformation orientations (continuously {001} hk0 ND rotated Cube orientations and {112} 110 Inverse Brass orientation). Such orientations arise due to the high friction during breakdown rolling, and do not change significantly during recrystallization [17,18].…”

A through-process texture and anisotropy prediction for AA5182 sheet production from hot rolling through cold rolling and annealing is reported. Thermo-mechanical process data predicted by the finite element method (FEM) package T-Pack based on the software LARSTRAN were fed into a combination of physics based microstructure models for deformation texture (GIA), work hardening (3IVM), nucleation texture (ReNuc), and recrystallization texture (StaRT). The final simulated sheet texture was fed into a FEM simulation of cup drawing employing a new concept of interactively updated texture based yield locus predictions. The modelling results of texture development and anisotropy were compared to experimental data. The applicability to other alloys and processes is discussed.
