Notes:
Symmetric three-layer composites prepared by sintering freeze cast compacts of alumina withadditions of nanoparticle/whisker SiC, in 1-atm nitrogen at 1700-1800oC have been characterized interms of microstructure and mechanical properties. Additions of SiC to Al2O3 result in improvement intoughness. In such cases, however, the reduction in strength at small flaw sizes must be overcome.Contact damage resistance is greatly increased in layered composites compared with monolithiccomposites, possibly due to redirection of indentation flaws along the layer interface
