“…Generally, materials with finer grains show better plasticity at room temperature [20]. In the present work, the improvement of elongation at 300 • C/30 min and 250 • C/120 min cannot be satisfactorily explained by the effect of average grain size.…”

Static recrystallization plays a key role in the fabrication of thin Mg wires as well as the mechanical properties of the final wires. The effect of annealing parameters on the evolution of the microstructures, textures and mechanical properties of cold-drawn pure Mg wire was studied by means of optical microscopy (OM), electron backscatter diffraction (EBSD), a tensile test and a hardness test. This study shows that the mechanical properties of as-annealed pure thin Mg wire is affected not only by the average grain size, but also the uniformity of the recrystallization grains, including the uniformity of grain size and crystal orientation distribution (more random texture component). With increasing annealing temperature and time, the uniformity of recrystallization grain size first improved and then declined after obvious grain growth. At the same time, the randomness of the basal texture component declined with the development of recrystallization. Annealing at 300 °C for 30 min caused the most uniform grain size and orientation distribution in the microstructures, thus contributing to the best plasticity among all experimental wires. It is reasonable to conclude that more uniform and regular recrystallized grains and a more randomly distributed crystal orientation would be benefit for the mechanical properties of Mg wires.

“…This result implies that the corrosion resistance of AZ61 alloy also depends on structural factors other than grain size. There have been several reports that the rate of corrosion decreases when the size of grains in Mg alloys decreases [23][24][25]. Song et al [26,27], however, reported contradictory results.…”

“…A great majority of studies on this topic have focussed on recycling machining swarf into cylindrical bars [3][4][5][6][7][8][9][10][11][12] or rectangular bars [13][14][15], using hot/warm forward extrusion. In addition, recycling processes based on other SPD methods such as cyclic extrusion compression (CEC) [16], equal channel angular pressing (ECAP) [17][18][19], high-pressure torsion (HPT) [20] or compressive torsion [21], and combined use of forward extrusion and ECAP [22,23] have also been reported.…”
