- The outstanding properties of ductile iron are due to a nodular or spheroidal form of precipitated graphite in the microstructure. - This favorable nodular graphite shape is obtained by treating with magnesium to retain residual Mg content within narrow control limits, then inoculating with ferrosilicon to nucleate that graphitization.

Selection of riser modulus and shape of nodular cast iron. The feeding riser must be large enough to supply additional liquid metal during liquid shrinkage until the temperature drops below the solid phase line and the parts begin to solidify. In the same way, the modulus can be used to evaluate the shrinkage of riser, MC is the modulus of ...

material selection, ... The mechanical properties and machinability of cast iron with nodular graphite greatly depend on the formation of graphite and the matrix microstructure and both are ...

is nodular iron which belongs to a group of available low cost materials. As a structural material it is highly competitive with other structural materials, steel in particular. Nowadays nodular iron is used for making vital machine and engine components such as, for example, crankshafts, camshafts, gears.

Welding-cast-iron deals with classes known as Gray, Malleable and Nodular (or Ductile) according to typical appearance of their microstructure, which affects their properties.. Cast irons are alloys of iron, carbon and silicon (may have over 2% carbon and 1-3% silicon), and may include specific amounts of other elements to achieve definite characteristics.
