摘要: 本工作采用了酸浸深腐蚀、热氧化腐蚀、离子刻蚀以及离子轰击深腐蚀等方法,对Fe-C合金中的石墨进行了腐蚀,并在扫描电子了显微镜下观察了石墨球和“蠕虫”状石墨的形态和结构。本工作揭示出球状石墨中心部分的形态并提出了有关石墨球构造的新模型。

Abstract: This Paper describes etching the graphite in an Fe-C alloy by using methods of profound etching in solution,thermo-oxideion etching,ionic etching and ionic bombarding profound etching.The topography and structure of graphite spheres and vermicular graphite has been investigated by SEM. This work describes the topography of the central zone of spheroidal graphite and a new model for the structure of spheroidal graphite.
