摘要
采用HT 2 0 0为实验材料 ,研究了微量元素Sb对灰铸铁石墨组织的影响 .研究结果表明 :灰铸铁中加入适量的Sb可明显减小石墨尺寸 .这种现象是由于增加了碳原子扩散阻力的结果 .
The effect of trace elements of Sb on the graphite microstructure has been investigated by using HT200 as the experimental material. The result of the experiment shows that the proper composition of Sb can reduce atom, the graphite in gray cast iron. This phenomenon can be enplained by the increase in diffusion resistance of carbon.
