| Abstract |
Finite element analysis (FEA) was conducted to find an optimum friction condition for cold-roll cladding of Al/Al-Mg/Al composite sheets. X-ray diffraction was used to analyze the initial macrotexture in each component layer of Al/Al-Mg/Al composite sheets. Electron back-scatter diffraction (EBSD) was used to analyze the heterogeneity of the deformation texture in each component layer through the thickness direction after cold-roll cladding. The velocity gradient tensors determined by the FEA were used in a rate sensitive polycrystal model to simulate the evolution of deformation texture through the thickness direction of Al/Al-Mg/Al composite sheets during cold-roll cladding. The theoretical simulation provided an optimum friction condition for cold-roll cladding analysis of the Al/Al-Mg/Al composite sheets. |
