4. Ductile iron - Wikipedia

   en.wikipedia.org/wiki/Ductile_iron

   Ductile iron is not a single material but part of a group of materials which can be produced with a wide range of properties through control of their microstructure. The common defining characteristic of this group of materials is the shape of the graphite. In ductile irons, graphite is in the form of nodules rather than flakes as in grey iron.
