Austempered Ductile Iron - Durham Foundry

Austempered ductile iron, also known as ADI or ausferritic ductile iron, is the most recent addition to the ductile iron family. It is produced by giving the conventional ductile iron a special austempering heat treatment. Nearly twice as strong as pearlitic ductile iron, ADI still retains high elongation and toughness.

Austempered Ductile Iron - Wikipedia

Austempered Ductile Iron (ADI) is a form of ductile iron that enjoys high strength and ductility as a result of its microstructure controlled through heat treatment. While conventional ductile iron was discovered in 1943 and the austempering process had been around since the 1930s, the combination of the two technologies was not commercialized until the 1970s.
