Ductile Iron Castings & Ductile Cast Iron
 
If cast iron is subject to a compressive load, these stress points are not particularly detrimental and flake graphite cast iron is excellent under compression. However, tensile loading above the natural tensile strength of the cast iron can cause rapid tensile failure as cracks propagate rapidly out from these stress points. The result of this is that cast iron has virtually no elongation, is a brittle material and is therefore limited in its use in tensile and shock loading applications. For years foundrymen and metallurgists tried to develop a new type of cast iron that would withstand bending and shock loading and would have the characteristics more of malleable cast iron but could be produced at the lower cost of grey cast iron. This resulted in the development of Ductile Cast Iron.

Properties of Ductile Iron

To create different grades of ductile iron, one must control the matrix structure around the graphite during the casting process or through subsequent heat treatment. The minor compositional differences between the different grades of ductile iron exist in order to create the desired matrix (microstructures).
Ductile iron can be considered as steel with graphite spheroids dispersed throughout its matrix. The qualities of the metallic matrix in which the graphite spheroids are suspended have a significant effect on ductile iron’s properties, but the graphite spheroids themselves do not.
 
There are several matrices found within ductile iron, the most common being;

  1. Ferrite – a pure, ductile, flexible iron with little strength. This matrix has poor wear resistance, but high impact resistance and good machinability.
  2. Pearlite – a mechanical mixture of ferrite and iron carbide (Fe3C). It is relatively hard, with moderate ductility. It has high strength, good wear resistance, moderate impact resistance, and good machinability.
  3. Pearlite/Ferrite – a structure consisting of a mixture pearlite and ferrite, and the most common matrix for commercial grades of ductile iron.
