An Al2 O3/Al ceramic matrix composite was fabricated by self-oxidation of pureAl+ NaOH,and its microstructure,mechanical properties and 9rowth mechanism wereanalyzed.Experimental results show that the composite possesses better mechanicalproperties,higher density and faster growth velocity than that made by Al-Mg-Si al-loy.The composite grows primarily along the crucible wall and has periodic wavy likestructure consisted with cell colonies.
