| 摘要: |
| 采用机械合金化方法,用行星式高能球磨机对Fe基合金中的Fe100-xPx(x=5,10,17,25,33,50,67)二元合金系统进行机械含金化研究,用X射线衍射仪分析球磨后的合金粉末结构,并用扫描电子显微镜分析样品的形貌和粒度。结果表明,用机械合金化方法可使Fe和P在P的成份小于20at.%时产生固溶体,在P的成份大于20at.%时有相应的化合物FeP或Fe3P生成;Fe-P系统在球磨lOOh后平均有效品粒尺寸约40nm,都达到了纳米量级;扫描电镜的形貌结果显示,粉末颗粒很细,但聚集成团。 |

| Abstract: |
| Mechanical alloying of Fe100-xPx(x=5,10,17,25,33,50,67) is performed with a high energy planet ball. The structure and morphology of milled powder mixtures are identified by X-ray diffraction and SEM, respectively. The results show that the iron solid solution appears when the shares of P are less than 20at%, and the intermetallic compounds FeP or Fe3P appears when the shares of Pare more than 20at%. The average grain size of Fe-Pas milled powders decreases to about 40nm after lOOh of milling. The aggregation of the fine powders can be observed under SEM. |
