For the Al-Mg alloy sheets, Zinc is selected to vary their stacking fault energy(SFE) of the alloys. The sheets with the thickness of 1 mm are produced with the conventional thermo-mechanical processes. That is, the cast alloys are homogenized at 430oC, cold-rolled, and then recrystallized at 430oC for 10 min. As the Zinc content in the range to 5 wt% increases, the SFE determined by the X-ray diffraction method decreases, providing the higher elongation to failure together with higher tensile strength although the grain size increases. Thus, with the variation of the SFE, the formation of cell structure observed using TEM in the early stage of plastic deformation is closely related, thereby affecting the work hardening behavior of Al-Mg-(Zn) alloy sheets. The detailed microstructure related deformation behavior will be provided.
