Abstract
Directionally solidified (DS) Al2O3/YAG eutectic composites with microstructures of three-dimensionally continuous networks were prepared using containerlessly directional solidification through an aerodynamic levitator. The morphological evolution of DS eutectics was studied at a large growth rate range. The DS eutectics present irregular “Chinese script” morphologies at growth rates of 9 μm/s, transforming into complex regular eutectic morphologies with growth rates increasing to 68 μm/s. At a superhigh crystal growth rate of 800 μm/s, the DS eutectics showed regular lamellar morphologies. The indentation hardness and Young’s modulus of DS Al2O3/YAG eutectic composites at growth rates of 68 μm/s are 22.3 and 338 GPa, respectively.
