| Abstract: | In this paper,the ZrB_2-SiC ceramic matrix composites were prepared by pressless sintering with YAG as sintering additive.The effects of additive content on mechanical properties and microstructure of the composites were investigated. The microstructure was analysized by SEM and EDS.The results show that YAG forms into glass phase with the impurity of raw at high tempreature ,the glass phase distributes in grain boundary and greatly improves the densification of the composites. |
