Casting (metalworking) - Wikipedia
In metalworking and jewellery making, casting is a process in which a liquid metal is somehow delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a 3-dimensional negative image) of the intended shape. The metal is poured into the mold through a hollow channel called a sprue. The metal and mold are then
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.

Inoculation of Cast Iron | Cast Iron | Iron
Inoculation is a means of controlling the structure and properties of cast irons by increa- sing the nuer of nucleation sites available for the growth of graphite flakes in grey irons or graphite nodules in ductile irons.This r educes undercooling during eutectic solidifiion thereby minimizing the risk of forming hard iron carbides or "chill" in the structure, parti- cularly in thin sections.
