Research Domain A: Optimisation of the formability of aluminium sheet with high secondary aluminium content
The aim of this area is to investigate and improve the formability of aluminium alloys with novel compositions, in particular alloys with high secondary aluminium content. Research focuses on the interplay between precipitation and deformation mechanisms to improve the ductility and workability of aluminium alloys. Microstructures will be systematically analysed to understand and optimise their role in the formability and strength of the material.
Research Domain B: Advanced Microstructure Characterisation
The focus is on the development of advanced characterisation techniques such as Scanning Precession Electron Diffraction (SPED) and High Resolution Electron Microscopy. These methods allow precise analysis of the microstructure and precipitation processes in aluminium alloys on the nanometre scale. By analysing phase and stress fields at the microstructure level, the complex relationships between deformation, precipitation and their effects on material behaviour are investigated.
Research Domain C: Process adaptation for microstructure optimisation in high strength precipitation hardening alloys
The aim is to develop new microstructures that improve the mechanical and corrosion resistance properties of aluminium alloys through targeted adaptation of process technology. In this area, the interactions between process parameters and microstructure development will be investigated and approaches will be developed to optimise material properties that can be transferred to industrial applications.
The scientific freedom complements the basic research by deepening and advancing the development of materials and methods.
On the one hand, fundamental mechanisms of deformation and microstructure development in aluminium alloys with a high recycled content are being investigated. Using in-situ X-ray diffraction experiments, the behaviour of the alloys under load is analysed to gain insight into lattice distortions, phase transformations and their influence on formability.
Another focus is the application of these findings to improve aluminium anode materials for energy storage devices in order to reduce the use of high-purity aluminium. This scientific freedom allows the laboratory to delve deeper into material dynamics and develop targeted adaptations for sustainable and high performance aluminium production, which is relevant not only for structural materials but also for energy storage.
