Optimization of AlMgMn- and AlMgSi-alloys for cryogenic deformation

In recent years the automotive industry focuses on the application of high-strength 5xxx and 6xxx alloys. In order to achieve sufficient plasticity and good surface qualities deep drawing processes are carried out at cryogenic temperatures.

The aim of this work is the optimization of AlMgMn- and AlMgSi alloys for cryogenic deformation. Therefore, the interaction of dislocations with various alloying elements and their clusters/precipitations should be observed.
