| Abstract |
A transformation dilatometer was used to formulate the dilatation amount of plain carbon steels during phase transformation as a function of carbon content and temperature. The mean carbon concentration in austenite during phase transformation could be calculated from the formulated equation and the mass balance of carbon in each phase. Through this calculation, a dilatometric characterization method, which can determine the volume fraction of each phase taking into account the effect of carbon enrichment in austenite during phase transformation, is suggested. The volume fractions of ferrite and pearlite and the beginning temperature of austenite-to-pearlite transformation, which were obtained from metallographic examination, were compared with the ones obtained by the developed dilatometric characterization method. |
