Abstract

A new route of severe plastic deformation – the complex shearing of extruded tube (CSET) technique – was proposed recently. In this route, a tube is produced from a rod via extrusion combined with two passes of an equal channel angular pressing like processing and with mandrel rotation. In the present paper, we describe and discuss the changes in the microstructure of an aluminum single crystal processed by CSET with respect to grain refinement, orientation changes and dislocation distribution.
