Oxidation behavior of Fe–Al–Cr alloy at high temperature: Experiment and a first principle study

Fe–Al–Cr alloys have excellent oxidation resistance at high temperature. Many studies have been carried out on their oxidation resistance mechanism, mainly on the role of Al, but there is a lack of understanding of the role of Cr. According to existing research results, the structure of the metal/oxide interface of Fe–Al–Cr alloys has been investigated by the density functional theory. Due to the third component, which is chromium, Al2O3 films...
