Abstract

Selective oxidation experiments of four iron-aluminum model alloys, containing 1-8. wt.% Al, at temperatures up to 1285. °C have been performed. The total corrosion depth and composition of formed nitride and oxide phases have been analyzed by means of SEM/EDX and XRD. Experimental findings and the interplay between formed oxide and nitride phases were compared to theoretical predictions from numerical simulations and critically discussed. Conditions for the formation of a continuous oxide band underneath the sample surface will be highlighted, which represent a critical parameter window in industrial processes that may lead to severe mechanical damage during rolling.
