The low density and the resulting potential for lightweight structural applications have already put aluminum and its alloys into the focus of automobile manufacturers for quite some time. Depending on the point of installation, different alloy classes are used in modern vehicles in order to take into account the occurring requirements. This selection of materials is often linked to a tradeoff between high strength and the associated safety on the one hand and high plastic deformation capability for efficient component design on the other hand.

To overcome this tradeoff, the approach of this research project is to use intelligent alloy design to implement the characteristically favorable properties of individual alloy families, e.g. To combine the outstanding formability of AlMg alloys (5xxx) and the extraordinary strength of AlZnMg alloys (7xxx) in new alloy variations and to generate the best possible use of their properties by developing suitable heat treatment strategies.
