Processing Techniques and Productions of Ductile Iron: A

2016-10-19 · Ordinary gray cast iron is characterized by a distribution of random lamellae of gra-phite in the metal matrix, while in nodular cast iron the gra-phite has the form of small spheroids. With respect to lamel-lae, the spheroids create fewer and less severe discontinuities in the metal matrix thus producing a stronger, more ductile cast material

cast iron into which inoculants are introduced under specific conditions in the liquid state. Inoculants with a modifying effect (ferrosilicon, calcium-silicon, carbon, aluminum, and alloys of titanium, zirconium, some lanthanides, barium, and strontium) make possible a reduction in the silicon and carbon content of cast iron without chilling and lead to the disintegration of graphite, thus

Technical Introduction to Inoculation of Graphitic Irons

This is called inoculation fade. The use of late or in stream inoculant (typically in sizes of 0.2 x0.7 mm, and often called GSK or MSI grade) or in-mould inoculation from cast block inserts reduces the chance for the particles to coalesce and additions of 0.05 to 0.1% can be used.
