Effects of Si, Mn, Ti and Ce on oxidation of Fe-Cr alloys in water vapour Open
Most high-temperature alloys are protected by chromia scales formed on their surfaces during service. Water vapour negatively affects the performance of these scales, an effect this work seeks to overcome. Binary Fe-Cr alloys containing 10…
