Kurzbeschreibung (Abstract)
Oxide dispersion strengthened steels ODS Eurofer and ODS 13.5Cr-0.3Ti were irradiated with 945 MeV Au ions and 167 MeV Xe ions at room temperature. Beam-induced microstructural changes were analyzed by high-resolution transmission electron microscopy in the region of maximum electronic energy loss of 55 and 30 keV/nm, respectively. In both ODS steels, an increase in the fraction of small oxide inclusions (<5 nm) was observed. In ODS Eurofer steel, the irradiation with Xe and Au ions leads to the formation of amorphous tracks in yttrium oxide inclusions larger than 8 nm with track diameters of 2 nm and 3–4 nm, respectively.
