摘要: 提出了一種由錐形螺旋體所組成的球狀石墨結構模型,同時給出了單個錐形螺旋體的主要剖面圖。每個錐形螺旋體中石墨的{0001}面繞著錐對稱軸連續螺旋生長,其〈0001〉方向近似乎行于錐對稱軸。Mg和Ce添加對石墨形核的影響也進行了討論。這一模型可以更好地解釋球狀石墨各種截面的組織特征,而且與實驗結果基本一致。

Abstract: A Mechanism of the G.S structure consisted of comical helixes is presented based on TEM, and the arrays of misoriented graphite platelets {0001} in each comical helix are believed to be grew up in spiral. The effects of Mg and Ce additions on the nucleations and growth of graphite are also discussed. The microstructure on the section of G.S observed earlier can be explained satisfactorily in term of the model.
