摘　　要：用高温金相的方法观察了经不同孕育处理的可锻铸铁试样表面的石墨化过程 ,讨论了固相石墨化的控制因素。Graphitization in solid state has been investigated.By the way of thermalmetallography we can observe the process of the graphitization occurring on the surface of the samples treated by different inoculantors.The factors of controlling the graphitization in solid stated have been discussed.

关 键 词：可锻铸铁 固相石墨化 高温金相 热处理
