Experimental investigation and thermodynamic consideration of oxide inclusions formation in Al-Mg alloys were done in this study. The surfaces of alloy samples right after the long time heating showed significant changes depending on the heating rates. Cross-sections of the oxidized samples air-cooled after the heating showed the existence of significantly formed pores and coarse oxide clusters near the surfaces. As a result of compositional analysis by a microscope on the oxide clusters, much higher contents of oxygen than other constituent elements were present in the oxide areas, indicating that the oxide clusters possibly contained a significant amount of gas. The compositional points corresponding to the oxide clusters were located in phase regions including MgO and spinel of isothermal Al-Mg-O ternary phase diagram.
