Castings made with spheroidal rather than flake gra-phite had high strength and ductility, good fatigue life, and impact properties.

weldinghandbook.com2.5.4 Nodular Cast Iron It is also known as “spheroidal graphite iron” or Ductile iron or High strength “Cast iron”. This nodular cast iron is obtained by adding magnesium to the molten cast iron. The magnesium converts the graphite of cast iron from flake to spheroidal or nodular form.
DUCTILE IRON PIPE
pe.mcwane.comDuctile Iron also differs from Gray Iron in that its graphite form is spheroidal, or nodular, instead of the flake form found in Gray Iron. This change in graphite form is accomplished by adding an inoculant, usually magnesium, to molten iron of appropriate composition during manufacture.

www3.nd.eduDuctile iron: small addition (0.05 wt..%) of Mg to gray iron changes the flake C microstructure to spheroidal that increases (by factor ~20) steel ductility 4. Malleable iron: traditional form of cast iron with reasonable ductility. First cast to white iron and then heat-treated to produce nodular graphite precipitates.

nickelinstitute.orgNi-Resist Austenitic Cast Iron Alloys There are two families of Ni-Resist austenitic cast irons. These are the standard or flake graphite alloys and the ductile or spheroidal graphite alloys. As time passes, the spheroidal grades, because of higher strength, ductility and elevated temperature properties, are becoming more prominent.
Metallography and Microstructures of Cast Iron

Sampling is the first step—selecting the test location or locations to be evaluated metallo-graphically. Usually, cast iron castings have a considerable variation in microstructurebetween surface and core. Selection of the test location is
