| Abstract: | 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. |
