Research Progress on Si 3N 4/SiC p Multi-Phase Composites

综述了ＳｉＣ颗粒弥散强化Ｓｉ３Ｎ４基陶瓷材料的研究近况，根据Ｓｉ３Ｎ４和ＳｉＣ的不同烧结机理对Ｓｉ３Ｎ４／ＳｉＣｐ复相陶瓷材料烧结机理以及ＳｉＣｐ的掺入对材料可烧结性的影响进行了理论上的探讨将ＳｉＣｐ粒子的尺寸对Ｓｉ３Ｎ４／ＳｉＣｐ复相陶瓷材料显微结构和力学性能的影响与材料可烧结性之间的关系进行了分析通过比较热压Ｓｉ３Ｎ４／ＳｉＣｐ复相陶瓷材料和Ｓｉ３Ｎ４／纳米ＳｉＣｐ复相陶瓷材料中ＳｉＣｐ含量对材料显微结构和力学性能的影响。

The development of SiC p particle reinforced Si 3N 4 based ceramics is reviewed.The sintering mechanism of Si 3N 4/SiC p composites and the effects of SiC p on the sintering behavior are studied according to different sintering mechanism of Si 3N 4 and SiC p.The relation between the influence of the size of SiC p on the microstructure and mechanical properties of Si 3N 4/SiC p composites and the sintering behavior of material is discussed.The reinforce effects and reinforce mechanism are discussed by comparing the influence of the amount of SiC p on the microstructure and mechanical properties of HP Si 3N 4/SiC p composites and HP Si 3N 4/nonaSiC p composites.
