Advanced mechanical properties of ODS steels are mainly due to the high number density of homogeneously distributed oxide inclusions. It is well known that some alloying elements like Ti, V, Zr, … play important role in oxide/nanocluster formation and influence on number density and size of these inclusions. In this work, we studied an ODS steel contained both vanadium and titanium. The ODS 12Cr-1.1W-0.2V-0.3Ti steel was characterized with TEM and APT. Different types of oxides inclusions were revealed in the steel: large (>70 nm) Ti2O3 oxides, small (~ 2–15 nm) Y-Ti-O oxides, and nanoclusters (2–5 nm). It was shown that the number density of these nanoclusters was considerably high than the one of the oxides and nanoclusters are enriched in Y, O, Cr, Ti, and V. Moreover, in spite of the fact that V and Ti are present in the material in approximately close value, clusters are predominantly enriched in Ti. APT samples of this material were irradiated with Fe ions up to ~ 8 dpa at room temperature. APT analysis of the irradiated material revealed decreasing of nanocluster number density with increasing their sizes. Changing in nanocluster composition was detected after the irradiation, but the decrease of Ti concentration in clusters was considerably less than the one for V. However, the Y/Ti, Y/(Ti + V), and (Ti + V + Y)/O composition ratios of nanoclusters remained stable under Fe ion irradiation to 8 dpa at room temperature.
