Abstract

ADI is the most recent development in the nodular iron family. With the austempering treatment, a unique microstructure named ausferrite is produced. This microstructure provides high mechanical strength combined with ductility, toughness and good fatigue and wear resistances. The aim of this work is to study the effect of alloying elements Cu, Ni and Mo on the mechanical properties and austemperability of the ADI. The addition of Mo decreased mechanical strength and toughness but increased both the wear resistance and austemperability.
