Abstract
In this work, rods of Al2O3–TiO2eutectics containing 65 and 60 wt% Al2O3were grown using the laser floating zone method. Raman spectroscopy was used to determine the phase composition. Creep strength of Al2O3–Al16Ti5O34(65AT) eutectic at 1500°C has 320 MPa, which is about higher thanβ–Al2TiO5/Al2O3(60AT) crystal. Temperature dependence flexure strength, hardness, elasticity and fracture toughness of the Al2O3–Al16Ti5O34andβ–Al2TiO5/Al2O3crystals were analyzed. The relationship between the microstructure and the mechanical properties were analyzed the 60 and 65AT eutectic crystals.
