Micromechanical simulation of fatigue in nodular cast iron under stress‐controlled loading
Material Design &Processing Communications, Volume 3, Issue 4, August 2021., 2021 Abstract Nodular cast iron contains about 10 vol% of graphite particles, which debond easily and thus act as nucleation sites of voids. When an elastic–plastic porous material is subjected to cyclic loading, voids grow with each load cycle due to so‐called void ratchetting until the micro‐ligaments between the graphite particles begin to neck.

Characterisation of PVD-TiN coated austempered ductile iron: Effects of nodule count and austempering temperature [PDF]
, 2011 In this work PVD-TiN coatings are deposited on ADI substrates austempered at 280 and 360°C, with nodule counts varying between 490 and 1 100 nod/mm2. The deposition is performed at 300°C by the arc ion plating technique.

Austempered Ductile Iron Machining
Technological Engineering, 2015 Abstract This article deals with the machining of cast iron. In industrial practice, Austempered Ductile Iron began to be used relatively recently. ADI is ductile iron that has gone through austempering to get improved properties, among which we can include strength, wear resistance or noise damping.
