Shears, Vortices, and Mixing During Twist Extrusion
Source abstract
Abstract
We present an experimental study of the kinematics of Twist Extrusion (TE) and show that TE has the following properties. As in ECAP, the mode of deformation in twist extrusion is simple shear. Unlike in ECAP, there are two shear planes; one of them is perpendicular and the other is parallel to the specimen axis. The following processes are present during twist extrusion: vortex-like flow with large strain gradient, stretching and mixing of metal particles. Twist extrusion opens new technological possibilities, e.g., decreased metal waster compared to ECAP, obtaining profile hollow specimens.
