The rolling of magnesium sheets is determined by multiple passes with low degree of deformation per pass. The necessity of keeping the degree of deformation per pass low is connected to the low formability of magnesium and its alloys. Alternatively, it has been shown that the extrusion of flat and thin plates is feasible.
By applying this process on alloys AZ31, ZE10 and ME21, thin sheets with final gauge below 1 mm have been achieved. A microstructure and texture analysis as well as the mechanical properties of these sheets reveals distinct differences compared to a classically rolled counterpart.
A series of Nakajima tests has been used to investigate the formability of the sheets. Forming limit curves have been derived at elevated temperatures. Strain path related differences in the formability at elevated temperatures of such sheets will be discussed based on an EBSD analysis of deformed samples for the alloys.
