Abstract Simulation was performed on repeated forging severe plastic deformation by “Deform-3D” finite element software. The distributions of flow, temperature, stress and strain during processing were analyzed. The results showed that the value and direction of flow velocity for each mass point were different during forging. The value of temperature rise in the same position of sample gradually decreased with the increase of initial forging temperature. Most area of the sample suffered compressive stress in three directions, and shear deformation which was beneficial to refine microstructure always existed. The strain distribution was inhomogeneous in the whole sample after the first pass of forging, and both accumulated strain and strain homogeneity improve as passes number of processing increased.
