文摘
- •
The Y2Ti2O7-dispersed Fe–Cr–Al alloys show enhanced oxidation resistance.
- •
Al plays dominant role in improving oxidation resistance by forming Al2O3 scale.
- •
Y2Ti2O7 nanoprecipitates are of importance to form stable Al2O3 scale.
- •
The concentration of Al in Fe-14Cr ODS alloy should not be less than 4.5 wt.%.
