High-temperature oxidation behaviour of Zr alloyed Fe3Al-type iron aluminide
Original language description
The oxidation behaviour of two Fe3Al-based Fe-Al-Cr-Zr-C alloys has been evaluated between 900 and 1200 degrees C. The alloys contained either (Fe,Al)(2)Zr Laves phase or ZrC carbide. The alloys were oxidised for up to 1000 h in synthetic air using thermogravimetric analysis (TGA). Scales that formed on the surfaces of the sample as well as cross sections were analysed by light optical microscopy (LOM), X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectrometry(EDS). At 900 degrees C parabolic growth and low weight gains for both tested alloys were observed. The scales are predominantly formed by Al2O3 with minor amounts of ZrO2. Some Fe2O3 was observed after oxidation at 900 degrees C. At 1000 degrees C oxidation ingresses into the samples along grain boundaries due to preferential oxidation of the Zr-rich precipitates, becoming more severe at higher temperatures. Ingress of oxidation into the sample is more pronounced for the alloy containi
