The Development of Research on Sulfidation Behavior of Iron Aluminides Intermetallics at High Temperature

Iron aluminides are expected to be a new high-temperature material, due to their good mechanical property and oxidation resistance at high temperature. Consequently,the sulfidation resistance of the material at high temperature is one of the most interesting subjects that are studied by materials researchers. Many factors have been confirmed to influence the sulfidation behavior of the iron aluminides intermetallics such as alloying component, corrosion atmosphere, temperature and pretreatment conditions. In this paper, the development of the research on sulfidation behavior of Fe-Al alloy is chiefly discussed from sulfidation mechanism, Al component in iron aluminides, REs, corrosion atmosphere and temperature respectively.
