摘要: 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.Abstract: In this paper MoSi2/SiC Composites have been densified using secondary hot-press technique, and the relative density of hot-pressed composites reaches up to 92%. The typical microstructure of hot-pressed composites examined by means of SEM and XRD is characterized by SiC particles uniformly distributed in MoSi2 matrix.
