“…Firstly, the amount and length of Al 2 O 3 columnar grains increased with the increase of sintering temperature. The toughening mechanisms of columnar grains had be concluded by crack deflection, crack branching and columnar grains pullout [9], which increased the crack propagation path and the fracture energy.…”
