用二次热压工艺改善了MoSi2／SiC复合材料致密度，热压复合材料相对密度可达到理论密度的92％.用SEM和XRD对热压复合材料组织结构的研究表明，热压复合材料组织为MoSi2基体上弥散分布着SiC颗粒．
The density of the MoSi2 / SiC composites was improved by the secondary hot pressing process, and the relative density of the hot-pressed composites reached 92% of the theoretical density.The SEM and XRD results of the microstructures of the hot-pressed composites show that the hot- MoSi2 matrix for the dispersion of SiC particles.
