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.
