Austempered Ductile Iron
Austempered Ductile Iron (ADI) is a type of ductile iron that is characterised by increased toughness, tensile strength and wear resistance compared to normal ductile irons. These properties are achieved by heat treatment of an alloyed ductile iron using an austempering process. The mechanical properties of ductile iron and ADI are primarily determined by the metal matrix.
