Magnesium as the lightest known metallic engineering material is offering an enormous potential for light weight constructions. Especially in automotive industries there is a demand for weight savings to fulfill requirements from the legislative to reduce CO₂ emissions, to save fuel and to provide materials that can be recycled easily. In the past magnesium cast alloys have been successfully developed and are fairly good introduced to vehicles even in power train applications with service temperatures up to 150°C and more. But there is still a lack of information regarding the use of magnesium alloys as wrought materials especially in sheet applications. This concerns both the availability of alloys and the processing parameters of a chosen wrought process. In the present study the cast magnesium alloy AM50 has been used to produce sheet by hot rolling. Preheated material has been deformed in several steps until the sheet reached a final thickness of 0.8 mm. Further deformation was applied on the sheets by deep drawing to get information of the materials behavior in a subsequent processing step. The paper describes the rolling and deep drawing experiments and the microstructure obtained after different steps of processing with a special regard to the recrystallization behavior.
