Term from 2006 to 2017
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 14208545
 
The main tasks of the Collaborative Research Centre are to use the whole potential of aluminium-based light constructural materials to manufacture security-related components in consideration of all influences during the whole process chain. Key points are the development, the manufacturing and the characterisation of new or innovative light constructional materials and their use in security-related applications.
Therefore, material concepts and processing has to be coordinated in such a way that the requested reliability over the whole product life cycle is guaranteed. The objective is to realise that security-related components necessitate a holistic conversion of a security concept, which includes all necessary specific security-related boundary conditions, as well as allow an essentially reduce weight and costs. The use of deformation processes for shaping is a key element to achieve outstanding mechanical values and high efficiency. The research activities will enable a requirement tailored design, manufacturing and finishing of aluminium-based light constructural materials.
One main focus is the development of high-strength forgeable aluminium alloys with an extreme dispersity to achieve a combination of strength and ductility, which was not accessible before.
Another focus is the development of particle reinforced Al-matrix-composites (AMCs) for high-temperature applications, because a precipitation hardening based strength is not effectually adjustable. As a third group of material Al-coated magnesium is used for the research activities.
These compounds distinguish themselves by a combination of high corrosion resistance of the coat and, in comparison to pure aluminium, a broad reduced density.
The extreme grain refinement in high-strength forgeable aluminium alloys is achieved through severe plastic deformation -SPD- in, for example, the ECAP (equal channel angular pressing) procedure. The gained improvement of properties for the manufacturing of semi-finished products has to be attuned to the conduct of the shaping and to further steps of surface refinement.
Because the performance characteristics are defined by the microstructure, the acquisition of basic knowledge for the thermal stability of the microstructure is the basis for a purposeful development. The applicability of the gained knowledge will be proved with demonstrator components from different branches of industry.
