Abstract:

The law of multi-directional flow was numerically simulated and experimentally investigated. Experimental results show that the metal around active mode follows priority deformation principle and has a strong directed deformation. The workpiece extruded by more directional active dies can not flow in all of deformation regions at the same time, but can be deformed alternately .The relationship between the defects  produced easily by the multiplex deformation and active mode position or movement direction was discussed. The simulation forecast and experiment results were consistent. The discovery can provide powerful evidence for recessional designing multiplex forming process.
