| Abstract | Al2O3/Er3Al5O12(ErAG) and Al2O3/Yb3Al5O12(YbAG) eutectic rods with fine and homogeneous microstructure, free from cracks or pores, were directionally solidified using optical floating zone method at growth rate of 10 mm/ h. The crystallographic orientation, preferred orientation, and 3D distribution of Al2O3 and Er3Al5O12/Yb3Al5O12 phases in the terminal growth zone of Al2O3/ErAG and Al2O3/YbAG eutectics were investigated by EBSD and high-resolution X-ray microscope. Vickers hardness of the as-prepared Al2O3/ErAG and Al2O3/ YbAG eutectics are determined as (13.5 +/- 0.4) and (12.8 +/- 0.1) GPa, respectively. The fracture toughness results of Al2O3/ErAG and Al2O3/YbAG are (3.0 +/- 0.2) and (3.2 +/- 0.1) MPa.m(1/2), respectively. |
