Microstructure of cast irons often consists of two totally different phases: Metallic matrix (like steel microstructures), and graphite with semi metallic properties. In the process of preparing the specimens for observing by TEM, maintenance of graphite particles before reaching adequate thinness is not quiet easy. In the present study, by choosing the specific techniques, it has been attempted to maintain the spherical graphites in their primer locations, while reaching extreme thinness. This leads to the ability of having a clear microscopic observation of the graphites' internal structure, especially on the outer layers. Further studies reveal these graphites; consist of a laminar internal structure with a special rotation pattern along crystal planes.
