Abstract

The mechanical properties of Y₂Ti₂O₇ ceramics have been systematically characterized. Y₂Ti ₂O₇ shows higher hardness (12.1 GPa) than Y ₂O₃ and TiO₂. The Young's modulus of Y ₂Ti₂O₇ (262 GPa) is close to that of TiO ₂ and 50% higher than that of Y₂O₃. The fracture toughness (1.9 MPa m^1/2) and bending strength (206 MPa) are comparable with those of Y₂O₃ but half those of TiO ₂. The indentation size effect on the hardness in nanoindentation tests is discussed based on the Nix-Gao model.
