| Abstract | Dynamic recrystallization of IN690 superalloy during tube extrusion has been simulated based on Cellular Automata (CA). The model of dislocation density and model of reply and model of nucleation and model of grain growth were determined. Morphology, distribution, orientation and size of grains during the process of deformation were obtained through dynamic recrystallization analysis. The results show that the grain size of the external wall is smaller than that of the middle under the same extrusion ratio. With the increasing of extrusion ratio, the grain size at the same site of the tube decreases. The relative errors of the grain sizes of simulation and experiment are less than 16.6%. |
