| 摘 要： | 基于相变动力学和热力学原理，并根据Schieil叠加原理和热膨胀实验结果，建立了形变奥氏体(γ)→铁素体(α)连续冷却相变动力学行为的预测模型，将其应用于形变奥氏体后的控制冷却过程，可以计算出铁素体相变开始温度以及室温组织中的体积分数等参数．该方法的计算模拟结果与实测结果吻合很好，表明这种理论的计算方法是可行的．

| Abstract: | Based on the transformation kinetics and thermodynamics, and according to the additivity rule for the progress of transformation, the predicting model of kinetic behavior of proeutectoid ferrite from deformed austenite after continuously cooling transformation was suggested. The model was used in the controlled cooling progress of the deformed austenite, which can find out the starting temperature of ferrite transformation, the volume fraction and the grain size of ferrite. The calculated results are in good agreement with the measured ones in the experiments, which shows the model is feasible. |
