摘要: 传统的把片状石墨看作孔洞与裂纹的观点,忽略了对片墨在断裂过程中的行为进行研究,因此,也限制了对铸铁本质认识的深化。本工作利用断口的电子显微分析方法,在对片墨在断口上的形貌特征进行系统研究的基础上,确定了片墨在断口上形貌的名称。并介绍了片墨在断裂过程中的基本行为和片墨表面观察到的大量的结晶学信息,得出了相应的结论。

Abstract: The conventional viewpoint takes flake graphite for voids and cracks, which neglects the studying of graphite fracture behavior. Therefore it limits the deepening of the understanding of cast iron nature. Based on the systematic study of flake graphite morphology on fractured surfaces by the use of electron microscopy. This paper has proposed the names of flake graphite morphologies on fractured surfaces. Described the basic behavior of flake graphite in fracture process and presented rich crystallization information. Correspondent conclusions have been obtained.
