Abstract: The need to minimize both material and energy losses in mechanical systems has led to an enlarged interest in the field of "Tribology", the. Science of friction, lubrication - and wear. The aim of the present investigation is to analyze the wear behaviour of dual phase steels in context of its' characteristic micro structure as observed in the configuration of a Ducom Machine. Examples are presented here of Ferrite-martensite mixtures designed for optimum combinations of high strength, toughness and wear properties. in Microalloyed steel, e.g. for mining, mineral processing, agricultural and pipe line Applications. In view of the above, dual phase steels are developed by intercirtical anealing treatment of Microalloyed steel at 740°C for holding time 15 min. Wear test done at different loads viz. 5.5, 6.5, 9.5 kg and sliding velocity ranging from 0.5 to 3.0 m/s. With increase in load the weight loss (wear) is observed to increase continuously but with an increase in sliding velocity it is observed to decrease in the range of velocities under investigation and to understand the wear mechanism, wear -tracks have been studied under SEM. It is observed that dual phase steel has superior wear resistance than that of as Received steel. It - is due to ferrittmartensite structure which exhibits high work hardening rate % and ,good.: toughness compared to ferrite-pearlite structure. iv
