摘　　要：基于热力学软件Thermo-Calc和动力学理论,建立了低碳钢在控制轧制和控制冷却生产中的微观组织演变物理冶金模型,回归了相应的力学性能模型。研究表明,预测的显微组织与实测值,以及计算的力学性能与实测值吻合较好。A physical metallurgy model based on Thermo-Calc of thermodynamics software and kinetics theory has been developed to predict microstructural evolution of low carbon steel after controlled rolling and controlled cooling,and a corresponding regression mechanical properties model has been put forward. It is shown that there is an agreement between the predicted microstructure and the measured value, and between the calculated mechanical properties and： the measured value.
