description The invention discloses a prediction method for microstructure evolution in a thermal deformation process of a Ti-6Al-4V titanium alloy, wherein the method is based on a cellular automaton theory and compiles a program capable of predicting the microstructure evolution in the thermal deformation process by utilizing Matlab software. Parameters in the thermal deformation process are input through the program, the microstructure, including the dynamic recrystallization integral number, the grain size, the grain morphology and the like, of the alloy after thermal deformation can be predicted, and the influence of different deformation parameters on dynamic recrystallization can be analyzed. Theoretical basis and technical support are provided for obtaining preset mechanical properties by controlling deformation conditions in the hot working process of the material. 本发明公开了一种Ti-6Al-4V钛合金热变形过程中的微观组织演变的预测方法，该方法基于元胞自动机理论，利用Matlab软件编译了一个可预测热变形过程中的微观组织演变的程序。通过该程序输入热变形过程中的参数，可预测热变形后合金的微观组织，包括动态再结晶体积分数、晶粒尺寸、晶粒形貌等，可分析不同变形
