Influence of small amount of Hf for oxidation of Fe-20Cr-4Al-S (185ppm) alloys

Influence of small amount of Hf for oxidation of Fe-20Cr-4Al-S (185ppm) alloys

Oxidation behavior of Fe-20Cr-4Al-S (185ppm) alloys with hafnium was studied in dry air at 1273K for 3600ks by mass change measurements, macro-morphology of oxidized surface, X-ray diffraction and scanning electron microscopy. The mass change of the alloy containing only 185ppmS was of 0.67×10-2kg/m...

Zusammenfassung:Oxidation behavior of Fe-20Cr-4Al-S (185ppm) alloys with hafnium was studied in dry air at 1273K for 3600ks by mass change measurements, macro-morphology of oxidized surface, X-ray diffraction and scanning electron microscopy. The mass change of the alloy containing only 185ppmS was of 0.67×10-2kg/m2. The mass changes of all the alloys increased in the order of the 900ppmHf
