摘要	The strength and fracture behavior of a directionally solidified Al2O3/Y3Al5O12 eutectic single-crystal were investigated. To identify and classify the toughening mechanism, fractography of the single-crystal was thoroughly analyzed. It was observed that the interfaces between Al2O3 and Y3Al5O12, which hindered the crack propagation, and nm-sized (111) cleavage planes appearing along the tearing ridge of Y3Al5O12 markedly improved the Al2O3/Y3Al5O12 eutectic single-crystal toughness. These results could improve understanding of the microstructure design and deformation mechanism of the Al2O3/Y3Al5O12 eutectic crystal. (C) 2017 Acta Materialia Inc. Published by Elsevier Ltd.
