Ductile iron - Wikipedia
Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron [1] and SG iron, is a type of graphite-rich cast iron discovered in 1943 by Keith Millis. [2]
Ductile Cast Iron | Density, Strength, Hardness, Melting Point
Ductile iron, also known as nodular iron or spheroidal graphite iron, is very similar to gray iron in composition, but during solidification the graphite nucleates as spherical particles (nodules) in ductile iron, rather than as flakes.
Nodular Cast Iron - an overview | ScienceDirect Topics
Nodular cast iron is a material that has found a increasing number of applications in the automotive industry during the last decade. It has a static strength comparable to cast steels and a greater fatigue strength and ductility than grey irons.
Ductile (Nodular) Iron – EngineeringTechnology.org
Ductile iron, also known as nodular cast iron or nodular iron, is a cast iron alloy with distinctive properties, including impact and fatigue resistance, elongation, and wear resistance. These properties arise from the spheroidal graphite structures within the metal’s microstructure.

2018年6月14日 · Nodular cast iron (also called ductile or spheroidal graphite cast iron) is much stronger and has a notably higher elongation than other grade cast irons. A relatively high strength and toughness of nodular cast iron are advantageous when it comes to numerous structural applications such as crankshafts, steering knuckles, brackets, valves ...
Mechanical Performance of Nodular Cast Irons After Prolonged …
2019年3月4日 · Ductile cast iron (DI), also known as nodular cast iron, is widely used in industrial applications for its good castability, low-cost and high range of mechanical properties that can be tailored for the specific application by modifying the matrix microstructure (Ref 1,2,3,4).
Mechanical Properties of Ductile Irons | Cast Iron Science and ...
Ductile iron, also known as nodular iron or spheroidal graphite iron, is second to gray iron in the amount of casting produced. This article discusses the common grades of ductile iron that differ primarily by the matrix structure that contains the spherical graphite.
Investigating the Material Properties of Nodular Cast Iron from
2022年9月9日 · The present investigation examines the metallurgical and mechanical characterization of a spheroidal (nodular) cast iron, an alloy that derives its name and its excellent properties from the presence of graphite as spheroidal nodules.
The mechanical properties of nodular cast iron with car-bides depend on the type of metal matrix and on the carbide content. The conducted studies have shown that surface con-tent of carbides higher than 5 % causes a significant decrease in plastic properties regardless of …
