| Abstract Scope |
Recent geopolitical events and the ongoing climate change demand for improved high-performance materials in energy technology, for example in future fusion reactors. 9%Cr reduced activation ferrite-martensitic steels like EUROFER are the material of choice, since it can withstand temperatures of 550°C as well as neutron doses larger than 20 dpa while still providing acceptable mechanical properties. The current study will summarize the results of a detailed microstructural characterization of several EUROFER97/3-type alloys by electron microscopy with mechanical properties and thermodynamic calculations. The single alloys slightly differ in their composition. In detail, the study will reveal the lath sizes by electron backscatter diffraction (EBSD). Furthermore, nanoscale transmission electron microscopy (TEM) measurements will reveal the number density, structure, and chemistry of nanosized precipitates. The microstructural data in combination will be related with the mechanical test results and with the thermodynamic simulation, which will provide a substantial basis for ongoing neutron irradiation studies. |
