Materials development for efficient energy conversion
Thermal and thermo-mechanical loads
The possible efficiency of modern energy conversion systems such as gas- and steam-turbine power plants or high temperature fuel cells is to a large extent determined by the process temperature. The experimental analysis and the simulation of the behaviour of application relevant materials and coating systems exposed to such loading conditions are the prerequisite for further increase in efficiency.
Corrosive gases and films
In combustion engines oxidative and corrosive atmospheres lead to material damage and failure.
Materials under extreme thermal loads
In future fusion devices high temperatures occur during transient and steady state heat loads (> 2000 °C). Special testing facilities allow the investigation of the materials under these conditions.
Constitution research and modeling
Materials change their texture, structure and subsequently their properties at high temperatures. The main focus of the research activities is on the prediction of structural properties after long term usage.
Metallography, X-ray diffraction as well as scanning and transmission electron microscopy allow the investigation of structure and structural changes from centimeter to picometer length scale.
Life time modeling
Modeling and simulation methods enable the development of life time models, which are essential for the component design.
Cooperation in the frame of the Helmholtz program takes place within the program for efficient energy conversion and usage (REUN), particularly in the topics power plant engineering and fuel cells as well as the program fusion (topic: ITER).
