Technically relevant structural high-performance materials, such as creep resistant steels and nickel based alloys for thermal power stations or microalloyed steels for applications in civil engineering, are based on extraordinary robust and stable microstructures and, therefore, provide superior properties. These properties are mainly determined by the chemical composition of the alloys and processing parameters, like forming processes and heat treatments, but initial properties and microstructures also may change during service exposure. The materials development group represents an interdisciplinary team, which focuses on the investigation and understanding of principle mechanisms which control and determine materials properties and service behaviour. For this purpose, the group utilises most advanced experimental and characterisation techniques, such as analytical transmission electron microscopy as well as powerful modelling and simulation tools. In combination with the broad experience of industrial project partners, this group is working to provide ideal solutions in materials design for all kinds of industrial applications.
