摘要：Austempered Ductile Iron (ADI) results from a special heat treatment of ductile cast iron. Using this
process, a phenomenal increase is observed in abrasion resistance and strength as well as toughness of the ductile iron.
Proper heat treatment gives desirable mechanical properties if high quality ductile iron is used as raw material of the
ADI. Different choice of heat treatment parameters result in different grades of ADI which have different physical
properties and behavior. The major responsible factor in the material for its physical strength, toughness and wear
resistance and hardness is its carbon content in various forms either free graphitized or combined with some other
constituent element like Cu, Ni, Cr, Mg or Si etc. The equivalent carbon percentage decides the nature of the obtained
material. This ranges from 4.3% to 4.6% in ADI. Due to combination of carbon with non-Fe constituents, carbidic ADI
is formed. The objective of current research is to analyze the effect of austenitizing temperature of 9750C on hardness,
micro-hardness, wear resistance and impact toughness properties of a specific combination of carbidicaustempered
ductile iron treated at different austempering temperatures and time duration.
