摘要：

The toughness of brittle ceramic could be enhanced by adding hard and strong inclusions. However, the interface between matrix and inclusions has to be weak. In the present study, a model system, Al2O3-Ti3SiC2 composite, is used to demonstrate that the toughness of ceramic can also be enhanced by using the reinforcement with weak internal layers. Titanium silicon carbide (Ti3SiC2) is a covalent bonded ceramic with weak internal layers. As 10-20vol.%Ti3SiC2 is added into Al2O3, both the strength and toughness of alumina are enhanced. The toughening is contributed mainly by the delamination of the weak layers within the Ti3SiC2 inclusions. (C) 2009 Elsevier B.V. All rights reserved.
