摘　　要：利用数据处理与理论推导相结合的方法建立了钢在完全再结晶区变形后奥氏体晶粒平均直径的预报模型。在模型中引进了微合金化元素Nb、Ti的影响，并对该模型进行实验验证及理论分析。The model to predict the average grain diameter of austenite deformed in complete recrystallization zone was established by means of combination of data processing and theoretical deduction. In the model, the quantitative effect of microalloying elements such as Nb, Ti was consideredAnd the model was verified to be practical by experiments.
