Twist Extrusion:Fundamentals and Applications

摘要：

We present a study of the kinematics of Twist Extrusion (TE) and show that the mode of deformation in TE is a simple shear. Unlike in EqualChannel Angular Pressing (ECAP), there are two main shear layers perpendicular to the specimen axis. TE has a significant commercial potential due to the following physical effects: intensive grain refinement; homogenization and mixing; intensive powder consolidation. Donetsk Institute for Physics and Engineering created a TE Center to showcase the process and educate investors. Our experience with the center has shown that the most prospective directions are producing ultrafine-grained (UFG) alloys for medical and aircraft applications.
