Abstract: Even since its discovery in 1948, the use of ductile iron is increasing continuously; this is due to the combination of its various excellent mechanical properties. Large amount of research is being carried out to develop even better properties. Austempererd ductile iron is the most recent development in the area of ductile iron or S.G. iron. This is produced by an isothermal heat treatment of the ductile iron. The formed austempered ductile iron is now replacing steel in many fields so it has becoming very important to various aspects of this material. In this work the effect of copper along with the process changes the properties and microstructure of ductile iron is studied. With changing austempering time hardness, tensile strength and elongation are changes but with increasing austempering temperature hardness and tensile strength are decreasing and elongation increasing. Austempered ductile iron with copper is very hard and lower elongation than the austempered ductile iron without copper. In microstructure ferrite is change with change austempering time and austenite is increasing with increasing austempering temperature in both the grades.
