Plastic Deformation Simulation on Compound Twist Extrusion Process for Metal Materials

Abstract:

Severe plastic deformation（SPD）methods have been the subject of intensive investigation for preparing bulk ultrafine-grained materials in recent years. This paper introduces a new severe plastic deformation (SPD) process named as C-TE process which combines the Twist Extrusion with Extrusion against the asymmetric deformation of TE process. and the distribution of effective strain and stress of the sample and the variation of load with time and its influence on the deformation were investigated by computer simulation with Deform-3D software . The results reveal that C-TE process can significantly slow uniform phenomenon,and a sample of homogeneous deformation can be obtained by the improved process.
