“…In addition, quantitative understanding of the underlying strengthening mechanism of cold deformed Mg alloy is of significant importance. For Mg and Mg alloys, cold deformations are mostly carried out via various kinds of forging, such as rotary swaging [ 6 , 7 , 8 ] and multi-directional forging [ 5 , 9 ]. Because the triaxial compressive stress condition of forging could help reduce crack and the strain rate can be better controlled, compared with rolling and extrusion.…”

Forging at room temperature was applied on the per-extruded Mg-Gd-Y-Zr alloy to investigate the effect of cold forging on the microstructure, mechanical properties and corrosion resistance of the alloy. Abundant micro shear bands with misorientations of 2–15° were generated in the as forged alloys. Tremendous enhancement in tensile yield strength was achieved after forging. With a quantitative investigation, micro band boundaries were considered to provide a great contribution to the reinforcement. The ultrafine structure resulting from the formation of micro shear bands led to increased corrosion resistance of the alloy.

“…Usually microhardness increases during SPD [10,17,29,[55][56][57][58][59][60][61][62][63][64][65][66][67]. It correlates also with tensile strength [13,24,25,57,60,[68][69][70]. It is true not only for rotation angle for HPT but also for number of passes during equal channel angular pressing (ECAP) [62].…”

<p class="AMSmaintext"><span lang="EN-GB">Severe plastic deformation (SPD) can induce various phase transformations. After a certain strain, the dynamic equilibrium establishes between defects production by an external force and their relaxation (annihilation). The grain size, hardness, phase composition etc. in this steady-state does not depend on the initial state of a material and is, therefore, equifinal. In this review we discuss the competition between precipitation and dissolution of precipitates, amorphization and (nano)crystallization, SPD-induced accelerated mass-transfer, allotropic and martensitic transitions and formation of grain boundary phases.</span></p>

“…Gan et al [33,34] studied the effects of swaging on commercially pure cast Mg and found progressive grain refinement and the tendency of the swaged material to form the (0002) basal texture. Wang et al [35] investigated the optimum swaging/annealing conditions for WE43 alloy and increased both, the strength and ductility of the alloy via swaging and annealing at 400 • C, and Martynenko et al [36,37] optimized the swaging treatment and reported the grains within WE43 alloy to refine down to 0.5 µm and the strength to increase to more than 400 MPa after severe swaging at temperatures between 325 and 400 • C. Several studies reporting the effects of FSP on Mg-based alloys have been published, but they are scarce. Wang et al [38] documented the positive effect of rotational speed of FSP on mechanical properties of the processed Mg-Zn-Y-Zr sample, Kumar et al [39] reported the positive influence of FSP on grain refinement within a laser-produced WE43 sample and characterized the varying strengthening mechanisms, Vargas et al [40] imparted significant grain refinement (grain size of 1.2 µm after single FSP pass and submicron grain size after the second pass) and ductility increase within Mg-Zn-Ca-Zr samples, Liu et al [41] homogenized the grain size and refined the grains down to approx.…”

The presented study deals with the investigation of biocompatible WE 43 Mg-based alloy processed via the combination of rotary swaging (RS) and friction stir processing (FSP) at three different rotational speeds of 400 RPM, 800 RPM, and 1200 RPM. The structure observations primarily focused on texture development and characterizations of grain sizes and grain boundaries. The results showed that swaging plus processing at 400 RPM and 1200 RPM lead to substantial recrystallization and grain refinement. The fractions of low angle grain boundaries within the 400 RPM and 1200 RPM samples were approximately 11%, while for the 800 RPM sample exhibiting secondary recrystallization it was about 22%. The grains were also the finest in the 1200 RPM sample (average grain diameter of 1.8 µm). The processed structures exhibited a slight tendency to form the {10-10} <0001> preferential fiber texture (especially the 800 RPM sample). Tensile testing showed the FSP to have positive influence on the ultimate tensile stress, as well as ductility of all the samples; the mechanical properties improved with increasing FSP rate.
