Room temperature microstructures, tensile properties, void formation and su
rface roughening due to deformation, forming limit diagrams (FLDs) and stra
in distributions in punch stretching in sheets of Al-Cu-Mg, Al-Mg and Al-Mn
alloys are described. The interdependence between the metallurgical variab
les and the mechanical properties is shown to be complicated. (C) 2001 Else
