把片状石墨看作孔洞与裂纹的传统观点,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。我们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丰富的结晶学信息,得出了相应的结论。 The flaky graphite as a hole and the traditional view of the crack, ignoring the film ink in the fracture process of behavior, therefore, also limits the understanding of the nature of the deepening of cast iron. Based on the systematic study of the morphology of the flake ink on the fracture surface, we used the electron microscopic analysis of the fracture to determine the shape of the flake ink on the fracture surface. The basic behavior of flake ink in the fracture process and the abundant crystallographic information observed on the surface of flake ink were introduced. Corresponding conclusions were drawn.
