The in-situ XRD analysis indicates that oxidation begins at 673K with the formation of MnO, ZnO, and CuO, follows by the appearance of Mn 3 O 4 and Mn 2 O 3 . It is found that the alloy shows improved antioxidation performance by forming continuous Al 2 O 3 film in the substrate near the interface of the oxidation film / matrix, but also shows susceptibility to detachment of oxide scale under high temperatures. It is revealed that there exists the phenomenon of the split of MnO diffraction peaks during the growth process of oxide film, which is proposed to be originated from the MnO produced by either the redox reactions of Mn 2 O 3 and Mn 3 O 4 with Mn or the replacement reaction of MeO (Zn, Cu, Ni, Fe) with Mn.
