Abstract

Al₂O₃/YAG unidirectionally solidified eutectic crystals were prepared by Bridgman method. Orientation relationships in the two phases were investigated by means of macroscopic (X-ray diffraction) and microscopic (electron diffraction) methods. Electron diffraction by TEM revealed that the growth direction of YAG was <100> crystallographically. The results of TEM observation showed that alumina had boundaries in crystal.
