2021119·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.

17/1/2011· An attempt has been made to evaluate the suitability of austempered ductile iron (ADI) as media material for grinding iron ore in a ball mill. Spheroidal graphite (S.G) iron balls are austenitised at 900 deg. C for 60 minutes and given stepped austempering treatment at 280 deg. C for 30 minutes and 60 minutes followed by 380 deg. C for 60 minutes in each case.
