文摘

To reasonably design the feeding strategy for radial-axial ring rolling process with material 42CrMo, the processing map of 42CrMo was constructed. The flow instability regions, ideal hot working domains and optimized deformation path were identified in the processing map. Based on this map, a desirable feeding strategy that could obtain a higher efficiency of power dissipation was determined by means of the subroutine VUAMP in ABAQUS. Moreover, a practical ring rolling experiment with the designed feeding strategy was carried out and the microstructure of the finished ring was also observed. The experiment shows that the deformed ring is rolled to the final dimension in a stable manner without macroscopic or microscopic defects, which indicates that the proposed feeding strategy is reasonable.
