Sulfidation iron aluminides

Properties such as good resistance to oxidation and corrosion (in particular sulfidation), low density (Fe3Al 6.5 g cm FeAl 5.6 g cm" ), inexpensive raw materials, and low content of strategic elements have driven the development of iron aluminides. [Pg.807]

Figure 6>16. In sulfidizing gases iron aluminides are significantly more resistant than alumina-forming FeCrAl alloys. Sulfidizing environment (Pq = 4 X 10" atm Psj = 9 x 10" atm) at 875 °C. For Fe-Al the transition to protective behavior occurred between 18.7 and 22 at.% A1 (data of Natesan, 1997). Figure 6>16.

Iron aluminides, including Fc3 A1 and FeAl, are of interest for high-temperature stmctural applications since they have relatively high melting points, excellent oxidation, carburisation, sulfidation, and hot corrosion resistance, relatively low density and low material cost. The major advantages that can be derived from the use of iron aluminides include the following [215,216] ... [Pg.382]
