| Abstract | Al2O3-Er3Al5O12 (EAG) eutectic composites was prepared by using Al2O3 and Er2O3 starting powders in arc melting furnace under the Ar atmosphere. Pulverized fine powders of eutectics were reinforced with different amount of ZrO2 addition which were then consolidated by spark plasma sintering (SPS) technique. The measured Vickers Hardness was in the range of 12,06-15,74 GPa and the fracture toughness of samples were found to be around 3,78-5,76 MPa .m. It was observed that the phases formed are distributed homogeneously in the material. The fracture behavior of the composites was found to be significantly improved with the addition of 20 wt % ZrO2 |
