into AM50 Mg alloys. Key words: Mg alloy; CaO; oxidation behavior; burning behavior 1 Introduction AM50 Mg alloy has already been applied to certain automobile parts, such as instrument panel, seat...] used EPMA and TEM analyses to study the CaO behavior in AZ31 and AZ91D Mg alloys. It has been confirmed that CaO in Mg-Al alloys was reduced to Ca and then Al2Ca phase formed without solid solution......
