Ductile Cast Iron Microstructure and its Influence on Mechanical Properties

The vast majority of modern structural components used in industry and power generation are made of ductile cast iron. One such kind of nodular cast iron is EN-GJS-400-18-LT which is especially used for the manufacture of dynamically loaded structural components. Due to fatigue loading, damage accumulates preceding in crack initiation and propagation which contributes to the overall failure of the structure. Well known fact is that the content of certain phases, i.e. ferritic and pearlitic as well as the size and shape of the graphite nodules influences significantly fracture toughness and fatigue life.
