An investigation of the mechanical damping of ductile iron ...

01-11-1995· Ductile iron has been suggested as a candidate material for a number of practical applications, including turbine castings, automotive components, and transportation and storage casks for hazardous and radioactive materials. The applications require the enhanced ductility resulting from the presence of spherical graphite nodules in the ductile ferrite iron matrix.

What is Ductile Iron? - Willman Industries

Ductile Iron is a type of cast iron known for its impact and fatigue resistance, elongation, and wear resistance due to the spherical (round) graphite structures in the metal. Ductile Iron is also called ductile cast iron, spheroidal graphite cast iron, or nodular cast iron. Learn more!

Ductile iron - Wikipedia

Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron and SG iron, is a type of graphite-rich cast iron discovered in 1943 by Keith Millis. While most varieties of cast iron are weak in tension and brittle, ductile iron has much more impact and fatigue resistance, due to its nodular graphite inclusions.
