Ductile Iron Quality Assurance Guide

- The outstanding properties of ductile iron are due to a nodular or spheroidal form of precipitated graphite in the microstructure. - This favorable nodular graphite shape is obtained by treating with magnesium to retain residual Mg content within narrow control limits, then inoculating with ferrosilicon to nucleate that graphitization.

Measuring Nodularity in Cast Iron - Olympus IMS

Application: Measuring the degree of nodularity in cast iron, or distinguishing nodular iron from gray iron. Background: Carbon in the form of graphite is often used as an additive in the production of cast iron, amounting to 2 to 4 percent by weight or 6 to 10 percent by volume in typical castings. The microstructure of graphite within cast iron has major effects on the casting's mechanical ...

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.
