Aim of this study is to perform relevant quantitative analysis of the observations during austempering of with or without copper in ductile iron. Ductile iron is a group of materials having wide range of properties and possessing controlled microstructure. Austempered-Ductile-Iron (ADI) is a relatively new material having exceptional combinations of mechanical properties and having potential applications. Researchers had tried to customize its properties mainly; yield strength (YS), percentage of elongation, ultimate tensile strength (UTS) and hardness by doping materials like copper in its microstructure. The present work highlights impact of austempering temperature and time on various mechanical properties of ductile iron and further emphasis to execute quantitative analysis for uncovering the affect of copper, effectively. Next General-Regression is applied to find relation of various properties with given Austempering metrics. High R (sq) value (0.80) signifies strong relations of properties with temperature and time, respectively and demonstrated empirically in terms of linear equations for drawing necessary implications for future research. The paper does not cover the images of microstructure or change in micro structural behavior during the austempering process of ductile iron. The paper also not covers the fractural behavior of ADI.
