High temperature oxidation of FeCrAl‐alloys – influence of Al‐concentration on oxide layer characteristics
TLDR
The superior high temperature oxidation resistance of FeCrAl alloys relies on the formation of a dense and continuous protective aluminium oxide layer on the alloy surface when exposed to high temp as discussed by the authors.Abstract:
