Al2O3-Y3Al5O12(YAG)-ZrO2 ternary composite rapidly solidified from the eutectic melt

In situ fabrication of new ceramic eutectic composites by rapid solidification of eutectic drops is a cheap and quick method compared to fabrication of directional solidification or multi-step fabrication methods of fiber reinforced/layered composites for high temperature use. This study reports the fabrication of ceramic composites during rapid solification of eutectics melts in the ternary oxide alumina-yttria-zirconia system. Layered ternary eutectics are obtained in the alumina-YAG-zirconia subsystem. The microstructure of Al2O3-Y3Al5O12-ZrO2 composites rapidly solidified from melts is presented.
