| 摘 要： | 采用主碳当量灰铸铁作为试验材料，以孕育处理的方式加入稀土和氮，研究了稀土，氮及二者复合能对石墨数量和石墨表面形貌的影响。试验结果表明，稀土和氮，特别是它们复合加入，使石墨百分含量减少；氮和氮与稀土复合孕育使灰铸铁的石墨表面变粗糙，且端部有钝化现象。 |

| Abstract: | By means of inoculanting, the effects of RE, N and RE N joint inoculants on the content and surface morphology of grphite of high C grey cast irons were studied. The results indicate that RE, N, especially RE-N joint inoculants could make the content of graphite decrease; N and RE N joint inoculants could make the surface of graphite rougher and the head of graphite flake passive. |
| Keywords: | RE N Inoculant Graphite Grey cast irons |
