“…It can be seen Previous studies Q%sching, 1995;David, 1989) have shown that iron aluminide claddings with ordered structures (i.e., Fe3Al and FeAl) are susceptible to hydrogen-induced (cold) cracking due to environmental embrittlement enhanced by residual stresses fkom welding. Intrinsically, bulk iron alurninides have been observed to be quite ductile when tested in vacuum or dry oxygen atmosphere at room temperature (Liu, 1991(Liu, , 1990(Liu, , 1989. However, the ductility dramatically decreases when tested in atmospheres containing moisture.…”

“…These low aluminum alloys lie outside the ordered region of the phase diagram, and thus lack the ordered DO3 phase which is often accompanied by brittle behavior. When the aluminum content is increased to between 20-27% Al, the ductility in inert environments drops down to 6% or less (1,16,18,61). The drop in ductility coincides with the appearance of the ordered phase.…”

“…In addition, testing in a pure oxygen atmosphere effectively stops embrittlement and often results in ductility exceeding that in vacuum (7,17,18,40). Liu, Lee, and McKamey (17) found that for a B2 ordered Fe-36.5%Al alloy tested in tension in various gaseous environments the lowest ductility was measured in laboratory air (2.2%) and H20 vapor (2.4%).…”

“…[6][7][8][9] The purpose of the present work is to investigate, by means of corrosion testing and microscopic examination, the effectiveness of Fe 3 Al-type intermetallic alloys as materials of construction for bath hardware in continuous lines. The corrosion behaviors of 316L stainless steel and two types of intermetallic compounds, Fe 3 Al and FeCrSi, in Galvanizing (Zn-0.18 pct Al), GALFAN* (Zn-5 pct Al), GALVALUME** (Zn-55 pct Al), *GALFAN is a trademark of International Lead and Zinc Research Organization, Research Triangle, NC.…”
