| 摘 要： | 用初始Ｍｏ粉和Ｓｉ粉通过自蔓延高温合成方法（ＳＨＳ）制取不同Ｍｏ５Ｓｉ３含量的ＭｏＳｉ２／Ｍｏ５Ｓｉ３复合材料．用Ｘ射线衍射仪、扫描电镜对产物进行组织结构分析．实验结果表明，在自蔓延高温合成中，ＭｏＳｉ２是一步生成，无中间相形成．随着样品中Ｓｉ含量的减少，产物中Ｍｏ５Ｓｉ３的含量增多，颗粒度变小

| Abstract: | The composites of MoSi 2/Mo 5Si 3 with different contents of Mo 5Si 3 were obtained by Self propagating High temperature Synthesis(SHS) from elemental powders of Mo and Si. The products were characterized by X ray diffraction and scanning electron microscopy. The experimental results indicated that in SHS, MoSi 2 was formed in a single step and no inter phases were found in the products. With the decrease of the contents of Si in the samples, the contents of Mo 5Si 3 in the products would increase and the particle size would decrease. |
