Introduction. Ausferritic spheroidal graphite cast iron is a cast alloy, iron and carbon based, carbon being present mainly in the form of spheroidal graphite particles. Compared with the spheroidal graphite castiron grades (see ISO 1083:2004 ), this material combines higher strength and toughness properties as a result of the austempering ...

Spheroidal graphite iron | metallurgy | Britannica
In metallurgy: Grain size. .casting, the result is a "spheroidal graphite" iron, in which graphite appears as spherical nodules and ductility is greatly increased. If the molten iron is chill cast (, rapidly cooled), it will form a "white" iron containing about 60 percent cementite, or iron carbide. This material is hard and wear ...

cast material, iron and carbon based, the carbon being present mainly in the form of compacted (vermicular) graphite particles that appear vermicular on a twodimensional plane of polish, the graphite particles being embedded in a matrix consisting of ferrite, ferrite/pearlite, or pearlite
Appliions
Although this graphite constitutes about 10% by volume of ductile iron, its compact spherical shape minimizes the effect on mechanical properties and results in a structure that is ductile rather than brittle, as is the case with normal flake graphite cast irons. This ductility has produced a cast iron which can perform in areas which ...
The 4 Types of Cast Iron
· Also known as nodular cast iron, ductile cast iron is a type of soft, ductile iron alloy with a high carbon content. It's typically made with trace amounts of other compounds, including magnesium and cerium. When added, these trace compounds inhibit the speed at which graphite grows, thereby keeping the metal soft and ductile. Ductile cast iron was invented in the early to .
Heat Treatment of Cast Irons | | Industrial Heating
12/12/2018 · Ductile or nodular iron, also known as spheroidal graphite iron, is cast iron in which the graphite is present as tiny balls, or spherulites, instead of graphite flakes (as in gray iron) or compacted aggregates (as in malleable iron). The nodular irons typically contain from % C, % Si and up to % Mn as major constituents.

The difference between gray cast iron and white cast iron
16/12/2019 · Gray cast iron is the most common and widely used cast iron. Its graphite is distributed in flake and the fracture is dark gray. The carbon content of gray cast iron is more than %. According to the position of chemical composition on FeC phase diagram, gray cast iron can be divided into subeutectic, eutectic and hypereutectic. ...
Mechanical Properties of Compacted Graphite Cast Iron
graphite cast iron, a material gaining increased acceptance for many automotive appliions, including exhaust manifolds, diesel engine blocks and heads, and brake components. Compacted graphite iron, shown in Figure 1, is a type of cast iron which has a graphite morphology intermediate to that of gray and ductile iron. As a result of its
Comparison of mechanical properties in flake graphite and ...
18/07/2013 · The mechanical properties of cast irons are to a great extent governed by the size, distribution and shape of the incorporated graphite particles. In a set of experiments, the mechanical properties of a pearlitic grey cast iron and a pearlitic compacted graphite cast iron are compared. Both cast iron grades have a eutectic composition.
Flake graphite cast iron
Flake graphite cast iron is predominantly produced with pearlitic structures, with the classifiion of grades being primarily determined by the graphite quantity and graphite shape and thus eventually by the carbon content. The higher the carbon content, the higher the graphite content in cast iron and the lower the strength values.
