Oxidation Behavior of FeCrAl - ODS Alloy in High Temperature Steam
At present, the evolution of oxide film structure of FeCrAl-ODS steel in the process of oxidation under high temperature steam is rarely studied. Taking FeCrAl - ODS alloy as the research object, using XRD, SEM, EPMA and EDS analysis methods, the high temperature steam oxidation experiment was carri...

| description | At present, the evolution of oxide film structure of FeCrAl-ODS steel in the process of oxidation under high temperature steam is rarely studied. Taking FeCrAl - ODS alloy as the research object, using XRD, SEM, EPMA and EDS analysis methods, the high temperature steam oxidation experiment was carried out at 700 ～1 100 ℃. The oxidation behavior of steam at high temperature was studied according to the oxidation kinetics and the structure morphology, phase and composition of the oxide layer. Results showed that the kinetics of high temperature steam oxidation of FeCrAl - ODS alloy met the parabolic law of weight gain at 700～1 100 ℃, and the parabolic rate constant Kp increased with the increase of temperature. After 96 h of high temperature steam oxidation, Fe2O3 was the main oxide layer on FeCrAl - ODS alloy surface at 700 ℃. At 900 ℃, Fe2O3 dominated outer layer and Al2O3 dominated inner layer of FeCrAl - ODS alloy surface oxide layer, and the loose oxide layer could not protect the substrate well. In the process of oxidation at 1 100 ℃, the oxide layer at different oxidation time was a monolayer of dense Al2O3 oxide layer structure. |
