Effect of cerium addition on tensile properties of Fe3Al-based alloys at ambient temperature

A small amount of Ce addition to FeAl alloys is noted to significantly improve their strength and ductility, especially in cases where combined amounts of Ce and Cr are used. XPS surface analysis indicates that Ce addition changes oxide chemistry, providing rapid passivation of the surface and minim...

Zusammenfassung:A small amount of Ce addition to FeAl alloys is noted to significantly improve their strength and ductility, especially in cases where combined amounts of Ce and Cr are used. XPS surface analysis indicates that Ce addition changes oxide chemistry, providing rapid passivation of the surface and minimizing environmental embrittlement. (AIAA)
