Abstract

The relationship between the Vicker's hardness VHN and the mean size of the coarsening cementite particles, ¯d in plain carbon steel during tempering at high temperature has been deduced and corroborated by experimental data analysis. It is found that VHN varies linearly with 1/¯d. Hardened plain carbon steel with 0.68, 0.56 and 0.34% carbon, has been tempered at 973 to 861 K as a function of time for the investigation. A master plot of VHN against ¯d(1−Vv)/Vv has been drawn which provides the mean particle diameter of the cementite particles as a function of hardness, irrespective of time and temperature of tempering and carbon content of the steel.
