低合金钢珠光体→奥氏体相变动力学

Phase Transformation Kinetics of Pearlite to Austenite in Low Alloy Steel

采用DSC法研究了低合金钢组织中珠光体!奥氏体的相变动力学。结果表明:该低合金钢的相变表观激活能为1141.04kJ/mol,其相变激活能随其相变体积分数的增加而逐渐减小。并在此基础上绘制了相变体积分数与温度之间的关系曲线。

The phase transformation kinetics of pearlite to austenite in low alloy steel was studied by the methods of DSC. The results show that the apparent transformation activation energy of pearlite to austenite in the low alloy steel is 1141.04 kJ/mol, and the phase transformation activation energy of pearlite to austenite decreases with the increase of the volume fraction of phase transformation. The relationship curves between the volume fraction of phase transformation and the temperature were drawn.
