摘要：
The corrosion behavior of Fe(5-20)Cr3Al2Si model alloys and the underlying mechanisms after breakaway oxidation was investigated at 600 ?. Rapid breakaway oxidation was triggered for all alloys in the presence of KCl(s). Thermogravimetric analysis showed that alloys with a Cr content of >= 10 wt% transitioned into sub-parabolic oxidation kinetics at an early stage of the oxidation process after breakaway oxidation. Through advanced electron/ion microscopy, this behavior was attributed to high Cr-enrichment in the bottom part of the inward-growing scale, indicating the formation of a healing layer. Additionally, alloys with elevated Cr-content (>= 15 wt%) were more prone to grain boundary attack.
