| Abstract: | The shaft upsetting process of the press has been simulated by use of FEM,and the deformation rules in upsetting process have been obtained.The simulation process accords with the theory.Then the microstructure transformation in the shaft upsetting process of the press has been simulated,and the growth law of crystal grain and the change of the dislocation density have been obtained,which discloses the forming rules of the upsetting process from the microstructure aspect. |
