摘要

This work presents a novel method for preparing an Al₂O ₃/YAG/ZrO₂ ternary eutectic whereby combustion synthesis melt casting has been combined with the ultra-high gravity (UHG) technique. The fabricated product had a relative density of 99.3% of the theoretical one. Phase composition and microstructure analyses indicated that the application of UHG resulted in a metal-free ceramic microstructure with no porosity or microcracks. The microstructure comprises ZrO₂ rods dispersed in Al ₂O₃. The product had 17.82 GPa Vickers hardness and 5.51 MPa·m^1/2 fracture toughness.
