| 摘 要： | 采用定向凝固液淬方法,并借助于金相显微镜和扫描电镜等手段,研究了铈含量的变化对铸铁中各种石墨间连续转变的影响。结果发现:在控制界面推进速度不变的条件下,随铈含量的增加,可以从片状石墨依次向过冷石墨、蠕墨、枝晶间石墨、球缺状石墨连续转变,而且这种转变是可逆的。

| Abstract: | The influences of content of ceriun on the continuous transition of various forms of graphites in cast iron were studied by means of directional solidification liquid-quenching, optical microscope and SEM. The results show that as the content of cerium is increased gradually, the flake graphite can transformed continuously into supercooled graphite, vermicular graphite, interdendrite graphite and sector-like graphite under a eonstent moving speed of interface between solid and liquid, and this transition was reversible. |
