red iron oxide (hematite or Fe2O3) to the sand mix. The use of magnetite or black (Fe3O4) grades of iron oxide were not nearly as effective in preventing porosity. The addition of nitrogen-stabilizing elements, such as titanium and zirconium, were effective, to varying degrees, in eliminating porosity.

Processing Techniques and Productions of Ductile Iron: A

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

Effects of Totally 48 Alloying Elements in Steel …

Silicon has a strong deoxidizing force, which reduces the magnetic aging effect of iron. When the silicon steel is heated in the oxidizing atmosphere, a layer of SiO2 film will be formed to improve the oxidation resistance of the steel at high temperature. Silicon can promote the growth of columnar crystals in cast steel and reduce plasticity.

Ductile Iron Data - Section 3 - Part 1

The increasing use of Ductile Iron components with as-cast surfaces places an increased importance on the elimination of surface defects for appliions requiring optimum fatigue strength. The reduction of dross-related surface defects through the use of filters in the mold filling system can result in a 25 per cent increase in fatigue life, as shown in Figure 3.31 .

01.12.2001· Strong nucleation effect and high nodule count are prerequisites to maximize the ferrite content when producing as-cast ferritic grades of ductile iron. The (Ca, Ce, S, O)-containing inoculant results in a bi-modal or skewed size distribution of nodules that aid in counteracting shrink and forming more ferrite by acting as effective carbon sinks in the segregated areas enriched in pearlite

from metallurgy to casting properties

Cast Iron quality is determined decisively by the applied melting practice, metal treatment and metallurgy. The prediction of feeding and structure formation of cast irons requires an accurate consideration of the microscopic phase separation, the foundries actual melt analysis and the type and effect of melt inoculation.
