ABSTRACT Nucleation of Fe-rich intermetallic phases on α-Al 2 O 3 oxide films were analyzed in five experimental Al-Fe-Mn-Si alloys. In an attempt to verify the role of α-Al 2 O 3 films in nucleating Fe-rich intermetallics, experiments have been conducted under conditions where formed in situ oxide films were present. Some Fe-rich intermetallics are observed to be related...
