Book Description
Plates of Austempered Ductile Iron (ADI) containing, in mass pct, 3.7 C. 2.7 Si, 0.97 Ni and 0.27 Mn were heat treated to ASTM 897 Grade 1 and 3 tensile properties and subjected to tensile testing at temperatures between -80 and 120 deg C. Room temperature yield and ultimate tensile strengths met specifications but values of elongation were lower than expected. The retained austenite contents contributed to lowered yield strengths during low temperature testing and increased ultimate tensile strengths and ductilities during high temperature testing. These changes in properties were related to the effects of temperature on the strain-induced transformation of austenite to martensite. The lower than expected ductility of the ADI specimens was related to microporosity, differences in graphite nodule distributions, differences in strain hardening related to austenite stability, and the ductile-to-brittle fracture transition of the matrix ferrite with decreasing temperature.

Book Description
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. Excessive 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 formed by an isothermal heat treatment of the ductile iron. The newly developed austempered ductile iron is now replacing steel in many fields so it has becoming very important to various aspects of this material. In the present work the effect of copper along with the process variables (austempering temperature and austempering time) on the properties (Hardness, Tensile strength and Elongation) and microstructure of ductile iron is studied. With increasing austempering time hardness, tensile strength and elongation are increasing but with increasing austempering temperature hardness and tensile strength are decreasing and elongation increasing. Austempered ductile iron with copper is showing some higher strength, hardness and lower elongation than the austempered ductile iron without copper. In microstructure ferrite is increasing
