与定向凝固或高温纤维增强/层状复合材料的多步骤制备方法相比，利用共晶液滴快速凝固原位制备新型陶瓷共晶复合材料是一种廉价、快速的方法。本文报道了三元氧化物Al_2O_3-Y_2O_3-ZrO_2系共晶熔体快速固溶法制备陶瓷复合材料的研究。在Al_2O_3-Al-Al_2O_3-Al_2O_3研究了熔体快速凝固Al_2O_3-Y_3Al_5O_(12)-ZrO_2复合材料的显微组织。©2005爱思唯尔有限公司。保留所有权利。
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 hi.-h 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. © 2005 Elsevier Ltd.
