New generation of ODS alloys
Original language description
Excellent creep strength of ODS steels is due to "sticking" of dislocations at nano-oxides. The aim of this study is to explore the Fe-Al-O and Fe-Al-Cr-Y-O systems with high oxygen content (up to 1.5 wt %) represented by alumina or yttria oxides (up to 5 vol. %) to identify the potentials of the new generation of ODS alloys. The basic material is prepared from Fe and 10 or 11 wt. % of Al. Theoretical models showed stability of Al oxides even above 1000°C, while practical results show coarsening with time at these temperatures. Stability of Y oxides is about 200°C higher, so there is a potential to have stable creep resistant alloy in range of 1000-1200°C.
