ADI is a material known for Impact toughness, hardness and wear resistance. CarbidicAustempered Ductile Iron [CADI] is a ductile iron which contains high wear resistance alloy carbides in its matrix and is produced by selecting proper composition of material through melting route. Two different alloy compositions of carbon equivalent close to the eutectic composition with variation in the chromium content are used in this study. A detailed microstructure characterization of the material is studied. Effects of austempering parameters on the mechanical properties like impact toughness, hardness and wear resistance are evaluated. Improvements in themechanical properties are found and are correlated with the microstructure. SEM analysis of the wear surface is also studied.
