However, other properties like irradiation resistance, corrosion resistance, fracture toughness, fatigue are also crucial for their applications. In this work, fracture behavior of 9%Cr ODS steels with no strengthening phase and with different composition of strengthening phase based on yttrium and aluminum oxides developed at IPM was evaluated. Fracture toughness testing was done in the temperature range from-100 to +550°C. All three variants of the steel demonstrated fully ductile behavior from the temperature -50°C. The results showed that presence of strengthening phase decreases fracture toughness and this effect is proportional to the effect of strengthening. The fractography analysis revealed no clear evidenceof fine strengthening phase on the fracture micromechanism.
