We develop structural and functional materials that can withstand extreme conditions. These include high temperatures and heat fluxes, as well as high-energy neutron radiation in combination with mechanical, chemical, or time-critical loads. The material properties are tailored by us for each specific application case. In this way, we open up new applications and areas of use in the field of energy conversion. Typical examples include components of a fusion power plant, such as plasma-facing components (divertor), heat exchangers (blanket), and neutron multipliers (tritium breeding elements).

Our research is application-oriented and, above all, takes place under the aspects of large-scale research. Therefore, alongside sustainability and cost-effectiveness, the focus is particularly on the use of industrial production, forming, joining, and manufacturing technologies. Starting from an idea, our materials development encompasses theoretical modelling, thermodynamic and thermo-mechanical simulations, production in the laboratory and on an industrial scale, experimental characterization of all relevant properties, microstructural and chemical analyses, the manufacturing of prototypes (semi-finished products and mockups), as well as component testing under the respective operating conditions. Our goal is to provide novel materials, including the materials technology process parameters and key characteristics required for production and component manufacturing.

Despite our focus on materials for very specific applications, the boundary conditions, requirements, and properties to be considered are very complex and diverse. So not all necessary investigations and experiments can be carried out within our department. Therefore, we collaborate closely with a variety of partners from KIT, industry, and other research institutions both domestically and internationally. In particular, the characterization and testing of prototypes requires access to large-scale facilities, such as test reactors for neutron irradiation: : HFIR, BR2, or experimental setups for the investigation of plasma-material interactions: HELOKA, ASDEX, GLADIS, JUDITH & JULE-PSI.
