Recently, the complex shearing of extruded tube (CSET) technique was proposed representing a new way processing tubes from bulk billet as combination extrusion with two passes equal channel angular and possible mandrel rotation. In present paper, influence rotation on final microstructure mechanical properties fabricated 3003 aluminium alloy investigated. Electron back scatter diffraction (EBSD...

An investigation has been carried out into the microstructures developed during the early stages of equal channel angular extrusion (ECAE) in a polycrystalline single-phase Al-0.13Mg alloy, with emphasis on the substructural alignment with respect to the die geometry and the crystallographic slip systems, which is essentially related to the grain refinement and texture development during deform...

The main limitation of the Equal Channel Angular Pressing (ECAP) is very high required punching force for pushing metallic sample to next channel. Frictional forces in ECAP process are responsible force. participation exit and entrance channels total friction has not been studied experimentally hitherto. Through current study, two dies (1) with (normal die) (2) only one channel (the was missed)...

This paper presents a finite element simulation of equal channel angular pressing (ECAP) since it is one the most common and successful severe plastic deformation techniques. study reports influence significant factors influencing ECAP technique. Through simulation, effect die geometry, workpiece speed on effective strain distributions, damage, loads, were investigated. The method different mat...
