摘要：

Isothermal high temperature tests have been performed on two B2 iron aluminides (a binary alloy and an ODS FeAl) in the temperature range between 750 and 1000 degreesC. The ODS alloy is elaborated by mechanical alloying with an Y2O3 dispersion to improve mechanical properties. Thermogravimetric measurements are carried out in high purity synthetic air, and the oxide film is studied by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results are compared with a recent analysis on similar binary and ODS FeAl alloys. (C) 2001 Elsevier Science Ltd. All rights reserved.
