- •
Oxidation of alloy 304 and 304-ODS steel in supercritical water at 650 °C/25 MPa.
- •
Weight gain of 131.8 and 621.6 mg/dm2 after 550 h for alloys 304-ODS and 304, respectively.
- •
The oxide scales on 304-ODS alloy composed of Fe3O4, FeCr2O4/(Fe,Cr)2O3 and Cr2O3.
- •
Oxidation followed a parabolic law for alloy 304-ODS and a cubic law for alloy 304.
- •
Formation of Cr2O3 transition layer is rate-limiting for oxidation of alloy 304-ODS.
