- Abstract
Differential scanning calorimetry (DSC) was used to study the transformation process of 1Cr13 steel under quenching condition. The DSC curves were measured from 1 050 °C to room temperature at the cooling rate of 10, 20, 30, 50 °C/min, respectively. The Flynn-Wall-Ozawa method was used to obtain the activation energy of the transformation process of 1Cr13 steel under quenching condition. The kinetic mechanism functions of the transformation process of 1Cr13 steel under quenching condition were also investigated by Criado-Ortega methods. The results show that the activation energy is related to the phase transition fraction. It means the transformation process of 1Cr13 steel under quenching condition is not a simple one-step reaction but a complex multi-step reaction.
