Al-Mg solid solution alloys of various grain sizes were prepared by
friction stir processing (FSP). The mechanical properties and
micro-structure evolution were studied. The results show that the
mechanical properties including tensile strength and ductility are
improved by increasing Mg weight fraction. The homogeneous
deformation is enhanced by fined slip bands within the grains. On the
other hand, Dynamic strain aging or serrated flow stress has been wildly
investigated in Al-Mg alloys. Effects of strain rate and magnesium
content on dynamic strain aging are also discussed.
