| 摘 要： | 利用 Auger 表面分析和化学分析等手段,研究了铸铁中磷在铁/石墨界面上的偏析及在铁相与石墨两相间的分配。实验结果表明,磷在球铁中有界面偏析现象,而在灰铁中没有发现偏析。磷在球铁和灰铁中的偏析特点正与硫在这两类铸铁中的偏析特点相反。

| Abstract: | Studied with AES and chemical analyses, the distribution ofphosphorus was found to be different between nodular iron and grey iron. Phosphorus atoms segregate at iron/graphite interface in nodular iron, while the interfaces in grey iron are free of phosphorus. Such different behavior of phosphorus between nodular iron and grey iron is opposite to that of sulphur. |

| Keywords: | cast iron phosphorus dislribulion segregation |
