摘要
An Al2O3 ceramic matrix composite was fabricated by self-oxidation of pure Al+NaOH, and its microstructure, mechanical properties and growth mechanism were analyzed. Experimental results show that the composite possesses better mechanical properties, higher density and faster growth velocity than that made of Al-Mg-Si alloy. The composite grows primarily along the crucible wall and its microstructure is characterized by a periodic wavy like structure.
