Twist extrusion (TE) is one of the most popular techniques of severe plastic deformation, aiming at imparting to a material a tailored microstructure and the associated property improvement. The article provides a survey of the literature on the mechanics of TE and the effect it has on the structure, texture, and the attendant properties of various materials, including metals and alloys, powder materials, and polymers. Special emphasis is placed on vortex flow during TE and its hitherto unexplored potential for producing micro-and macrostructures that promise superior properties of the materials. In particular, the possibility of creating novel hybrid materials with chiral inner architecture is demonstrated. The survey is concluded by a presentation of examples of practical applications of TE.

“…[20] It was shown that with increasing number of TE passes, cross-flow gives rise to a vertex in which an entire cross-section of the specimen is involved. [22,23] The viability of this approach was recently demonstrated for conventional torsion, [24] highpressure torsion, [9] and TE. According to a seminal work by Bouaziz, armoring a metal with spiral-shaped fibers can produce a dual effect of strengthening and increasing elongation to failure.…”

“…[49] Such hybrid designs are particularly promising as a way to increase the resistance of a material to crack propagation. [24] After unrolling the cylinder armored with the fibers to a plate with embedded thin layers, one can apply the above calculation. [9] For that, such a composite can be represented by coaxial cylindrical shells one of which hosts the spiral elements.…”

Synthesis of Hybrid Materials by Severe Plastic Deformation: A New Paradigm of SPD Processing

2015

An emerging direction of research into severe plastic deformation (SPD), which we refer to as SPDinduced synthesis of hybrid materials, is presented. At its core is the creation of inner structure made from various materials within the bulk of a solid. As distinct from the traditional metal forming, SPDinduced synthesis produces an engineered inner architecture of the solid without changing its exterior geometry. The possibilities of the SPD techniques with regard to materials synthesis are demonstrated. Research in this nascent area will open up new avenues for fabrication of advanced hybrid materials, while also posing a number of challenging scientific problems. A particular application discussed concerns the development of hybrid ultrafine-grained materials with enhanced structural ductility.

“…In particular, the emerged paradigm of architectured materials offered an invigorating stimulus to the area of severe plastic deformation (SPD) technologies [5,6]. Not only can these technologies produce a submicron scale grain structure that provides metals and alloys with exceptional mechanical performance, but they can also be used to form various inner architectures of a workpiece at a mesoscopic and macroscopic scale [7][8][9][10][11]. In this regard, the SPD methods involving plastic torsion, such as high pressure torsion (HPT) [12,13], incremental HPT [14], twist extrusion [15], shear extrusion [16], high pressure torsion extrusion (HPTE) [17,18], torsion extrusion [19], three roll planetary milling [20], spiral equal channel angular extrusion [21], tandem process of simple shear extrusion, and twist extrusion [22].…”

High pressure torsion extrusion (HPTE) is a promising new mechanism for severe plastic deformation of metals and alloys. It enables the manufacture of long products with a radial gradient ultrafine-grained structure and of composite materials with a helical inner architecture at the meso and the macro scale. HPTE is very promising as a technique enabling light weighting, especially with magnesium, aluminium and titanium alloys. For the first time, this article presents an analytical model of the HPTE process that makes it possible to investigate the role of the various process parameters and calculate the distribution of the equivalent strain over the entire sample length. To verify the model, its predictions were compared with the numerical simulations by employing the finite element software QForm. It was shown that potential negative effects associated with the slippage of a sample relative to the container walls can be suppressed through appropriate die design and an efficient use of the friction forces.
