Features of Twist Extrusion: Method, Structures & Material Properties

Plastic flow, structure and mechanical properties in pure Al deformed by twist extrusion

“…Twist extrusion (TE) is known as one of newly developed SPD methods [1,5]. TE was introduced by Beygelzimer et al [7][8][9] in 1999, but it is still studied moderately. Therefore, this research was initiated to study development of structure-property relationship with twist extrusion processing.…”

Comparison of microstructure and mechanical properties of pure copper processed by twist extrusion and equal channel angular pressing

“…In ECAP processing materials are used in various forms of rod, bar or even sheet, while in HPT method sample shape is limited to thin disks. TE [4] is an another conventional SPD technique which is similar to HPT processing but it is performed on billets with an arbitrary crosssection (except for circular). It was shown that during TE processing each physical cross-section of a billet is deformed in the same way as a thin disk during HPT processing is [5].…”

The effects of post annealing on the mechanical properties, microstructure and texture evolutions of pure copper deformed by twist extrusion process

“…Twist extrusion (TE) is a novel technique, belonging in the SPD category, which has been developed in recent years [3,4]. It is based on extruding a billet under hydrostatic pressure through a twisted channel including a rotation angle (˛) and a slope angle (ˇ) (see Fig.…”
