Modelling of components made of rolled and annealed aluminum sheets with particular properties for the automotive industry
The project topic covers the display of the entire process chain for the production of rolled sheet material from aluminium through simulation models and thus it shall enable to pursue simultaneously chosen properties.
Microstructure Modelling in Forming Processes
The project topic includes the modelling of the microstructure at forming processes; by means of numeric simulation models the layout of new as well as the optimisation of already existing process chains shall be enabled. The target is to be able to predict important product properties, especially regarding microstructure resp. grain size distribution.
Increasing requirements on rolled products and casting components from aluminium can only be met through continuous material development and qualitatively most significant products. Materials, poor in non-metallic impurities and showing sound, homogeneous surfaces, accomplish significantly better mechanical properties and even with cyclic load lead to a longer lifetime and optimised strength.
Sustainable Recycling Concept: Efficient Melting
In the last years an increasing trend for the optimisation of technological processes regarding energy efficiency and environmental sustainability could be noticed. Within this research cluster the optimisation of the recycling process of aluminium is investigated. One of the main targets is the development of a model for the aluminium recycling process. Among others it shall contain the mapping of liquid and gas reactions as well as the fluid dynamics and thermal conditions in the recycling process.
Hot Distortion of Sand Cores during Casting
The dimensional stability of castings is essentially influenced by the distortion of the laid sand cores during casting. This up to now only little considered part of the casting process becomes more important, especially through the increase of inorganic binder systems and the process conversion caused by this. Therefore the targets of the project are to understand and – via simulation - predict especially the distortion of sand cores and the distortion-relevant essential variables for the dimensional stability of the component.
