Abstract:The lamellar structures of Al/Al2O3 composite and the basic characteristics of directed metal oxidation in Al-Mg-Si alloy were discovered, the importance of the volatilization of magnesium to the process of directed metal oxidation was identified, and the volatilization mechanism of magnesium was put forward. By means of the model, the several important items were discussed.

 

Key words: directed metal oxidation; volatilization; magnesium; lamellar composite
