| Abstract: | By integrating the thermomechanical coupled FEM with mathematical model ofmicrostructure evolution, the pa- per proposes a numerical prediction method for microstructure during hot deformation. As an application, the microstructure evolution of H beam during hot rolling is simulated. The co- incidence of the predicted grain sizes with measured ones show that the method is able to successfully predict the microstruc- ture of metals after hot deformation. |
