Due to their high specific mechanical properties, magnesium sheets offer a significant weight saving potential in modern vehicle constructions. To increase the range of applications e.g. in the automotive industry, deep-drawn magnesium sheets have to comply strict requirements regarding corrosion resistance, geometric tolerances, forming capacity and surface quality . Furthermore the developers of a process-chain for the fabrication of magnesium sheets have to ensure cost effective and environmental friendly production steps in order to compete with alternative materials such as aluminum, modern steel-alloys and plastics.
The standard process-chain consists of slab-casting, rolling (incl. heat treatment), deep-drawing, joining, corrosion protection and enameling . The present article covers new basic approaches to improve the rolling-process in order to suit the criteria mentioned above. The first part summarizes the research work conducted at the Institute of Materials Science (IW) at the University of Hanover concerning the rolling process. Besides basic parameter studies on thin magnesium strips, sample sheets were produced. The second part of the article covers the mechanical properties-testing and deep-drawing experiments of these sheets which took place at the Institute for Metal Forming and Metal Forming Machine Tools (IFUM) at the University of Hanover.
