摘要：
The oxidation behaviors of Fe22Cr5Al3Mo-xNb (x=0.5, 1.0, 2.0 wt%) alloys under simulated loss of coolant accident (LOCA) conditions at 1000 and 1200 degrees C were investigated. The results revealed that fine granular oxides and a ridged oxide film were formed on the FeCrAl alloys at 1000 and 1200 degrees C, respectively. The oxide film was composed of alpha-Al2O3, alpha-Cr2O3 and a trace amount of FeO at 1000 degrees C but only consisted of alpha-Al2O3 at 1200 degrees C due to volatilization of Fe and Cr oxides. Nb addition decreased the weight gains and improved the oxidation resistance of FeCrAl alloys under simulated LOCA condition.
