| 英文摘要 | Al2O3/Y3Al5O12(YAG) directionally solidified eutectic (DSE) crystal was prepared by optical floating zone technique. A1(2)O(3)/YAG DSE consists of continuous entangled Al2O3 and the YAG forming a three-dimensional networks structure. The volume fraction of porosity is ultra-low (0.013%) and the average equivalent diameters of most pores (> 84%) are smaller than 4 mu m. The Al2O3/YAG DSE shows excellent high-temperature elastic stiffness. The Young's modulus at 1500 degrees C maintains more than 85% of the value at room temperature. Bending strength exhibits excellent retention up to high temperature as well. High-temperature ball indentation testing shows plastic deformation involving dislocations and twinning, which predominantly occur in A1(2)O(3) phase, while the YAG phase is stable. Evaluation on H-v/E index predicts A1(2)O(3)/YAG DSE with moderate capability to accommodate damages. Our results highlight A1(2)O(3)/YAG DSE as excellent high-temperature structural materials. |
