Evolution of deformation texture in Al/Al-Mg/Al composite sheets during cold-roll cladding

Al/Al-Mg/Al composite sheets were fabricated by roll cladding to investigate the evolution of deformation texture through the thickness direction. Electron backscatter diffraction (EBSD) was used to analyze the heterogeneity of deformation texture in each component layer of the composite sheets. Finite element analysis (FEA) was conducted to simulate the deformation history in each component layer during roll cladding. The deformation history from the FEA was used in a full-constraints polycrystal model to simulate the evolution of deformation texture through the thickness direction during roll cladding. The simulation results revealed that the development of distinct shear-strain texture components in the clad layer could be explained by the friction-induced shear component of a velocity gradient tensor.
