高壓扭轉(zhuǎn)IF鋼壓縮階段的不均勻變形
[Abstract]:The uneven distribution of hardness and microstructure during high pressure torsional compression of if steel was observed and studied. The experimental results were simulated and verified by ANSYS finite element analysis software. The results show that the distribution of stress, strain and hardness of if steel during high pressure torsional compression is not uniform: the center deformation degree is smaller, the hardness is lower, the middle zone deformation is more uniform, the hardness tends to be consistent, and in the edge region, the distribution of stress, strain and hardness is not uniform. The deformation degree is very large and the hardness is relatively high. For the limited high pressure torsion, the deformation "dead zone" is formed because of the block effect of the vertical wall of the die grooves on the specimen deformation. The simulation results are in good agreement with the experimental results of hardness and microstructure distribution, which shows that the uneven distribution of microstructures and hardness is due to the uneven deformation of various parts of the specimens during compression.
