Popis: |
Alumina/yttrium-aluminum garnet (YAG) and alumina/yttrium-aluminum perovskite (YAP) eutectics were made by directional solidification. The two systems were characterized using transmitted polarized light microscopy, scanning electron microscopy, and transmission electron microscopy. The alumina/YAG system exhibited a degenerate eutectic with a Chinese script morphology, while the alumina/YAP eutectic had a rod/lamellae morphology. The c-axis of alumina was aligned perpendicular to the solidification direction, and elongated grains were aligned along the solidification direction in both systems. A single orientation relationship between alumina and YAG was observed. Several orientation relationships were observed in the alumina/YAP system. 5 refs. |
