Paper Title:
Research on the Forging Penetration Efficiency of 40Cr Axial Forging by the Simulation of Dynamic Recrystallization
  Abstract

The property of Heavy axial forgings can be modified by the reasonable drawing process with the advantage of dynamic recrystallization. In view of formation, heat transfer, heating generation, dynamic recrystallization a macro-micro coupled process was modeled, and the drawing process of φ300 mm×4000 mm axial forging is simulated .It is found that when the cumulative reduction ratio reaches 9% in the second round, the dynamic recrystallization occurred in the material as it reached a critical strain condition .With the reduction ratio increases, the volume fraction of dynamic recrystallization increases. When the cumulative reduction ratio reaches 60%, about 67% of the inner region of the axial forging is modified fully. After the drawing process, the dynamic recrystallization grain size in 60% of the cross-section area is less than 100 μm , and the grains get refined.
