History - Applied Process
Also in that year, the process was first commercially applied to produce Austempered Ductile Iron (ADI) at an Atmosphere Group facility. Each of these equipment and process developments increased the productivity of the austempering process and drove down the price, making it competitive with conventional heat treatments.

Ductile iron is actually likely to expand during the casting process, as shown in the table found on the Casting Wikipeda page, which is in part cited from this casting text by Stefanescu. However, as the tables show, the range of volume change is fairly large and not one-sided, which is to say the ductile iron may either expand or contract depending on other conditions of the casting process.

Technical Information | SG Castings - Ductile Iron Foundry
In grey iron this graphite is in the form of flakes, but in ductile iron the graphite particles are nodular. This composition means that the metal has a very low propensity to crack - the nodules actively inhibit the process of cracking meaning the material has much more ductility - hence the common name of ductile iron.

Strength of Ductile Iron - Compared With Steel? - …
Ductile iron is used for a nuer of appliions such as crankshafts because it is extremely resistant to abrasion, much more so than steel. The main reason for this is the higher graphite content. As the ductile iron wears away, it creates graphite dust that acts as a lubricant, just like when a Cub Scout puts a little graphite dust on the axel of his pinewood derby car.
