What is the Microstructure of Grey Cast Iron

Grey iron has graphite flakes entwined with the rest of the structure. Unhardened grey iron is “fragile” compared to other cast metals.  The graphite flakes create areas of weakness in the metal where fractures can begin that will split the metal.  This propensity to fracture is why grey iron has low tensile and impact strength.  Yet the graphite flakes are what create great wear resistance because as friction occurs the graphite acts as a lubricant.  The graphite structure also has great vibration dampening properties because the structure created by the graphite flakes helps cancel out vibrations.
