| 摘要: |
| 为了解渗硼层硼化物的生长过程,采用系列磨片和计算机三维重建技术与可视化,研究了纯铁渗硼层硼化物的立体形貌．结果表明:渗硼层的硼化物以柱状晶形式向基体生长,同时柱状晶也在横向生长,纵向生长速度大于横向生长速度;处于表面的柱状晶根部连在一起形成连续的渗硼层,柱状晶生长过程中会出现倾斜和合并;三维形貌的二维剖面形貌呈齿状,与实际二维金相组织一致;从不同剖面方向观察同一硼化物,硼化物形态不尽相同,二维图像不能完全反映硼化物的真实形貌． |

| Abstract: |
| To fully understand the growth process of iron boride, the three-dimensional morphology of boride layer on armco iron was revealed by means of serial sectioning and computer-aided three-dimensional morphology reconstruction and visualizaed techniques. The results show that the morphology of iron boride is columnar growth to the interior of the iron substrate. The longitudinal growth rate of columnar iron boride is greater than the cross-sectional growth rate, the root of columnar iron boride in the surface layer of specimens connects together and forms boride layer, and the columnar iron boride appears inclination and mergence in growth process. The cross-sectional view of three-dimensional morphology is saw-toothed and consistent with two-dimensional microstructure of boride layer, and the two-dimensional morphology of boride layer is diverse while it is observed from different sections. The real morphology of iron boride could not be showed completely by 2D section. |
