| 摘 要： | Ｓｉ３Ｎ４／ＳｉＣＵ纳米复合陶瓷是近年发展起来的高温高温度结构材料，它通过纳米ＳｉＣ颗粒在Ｓｉ３Ｎ４基体中的弥散达到强化增韧的效果。研究表明，这种增韧方法所获得的室温和高温机械性能均远远高于其它的增韧方法。本文综述了Ｓｉ３Ｎ４／ＳｉＣ纳米复合陶瓷在制备、结构和性能方面的研究成果，指出了尚待解决的问题和今后的研究方向。

| Abstract: | Si3N4/SiC nanocomposites are the materials of high strength and high operating temperature developed in recent years, which are reinforced by nanosized SiC particles dispersed in Si3N4 matrix. Researches have shown that these materials have much higher mechanical properties than those toughened by other methods at both room and high temperatures sIn this paper, the preparation, microstructure and properties of Si3N4/SiC nanocomposites are reviewed. The existed problems and the future research directions are pointedout. |
