“…Furthermore, it is found that the dynamic recrystallization (DRX) occurred, as shown in Fig. 4b, d, f and h. DRX has an important effect on refining the microstructures [19][20][21]. Secondary phases were broken and then were distributed along the extrusion direction.…”

“…1(d), which indicates that quantities of substructures with LAGBs distribute the grains. Yang et al [8] indicated that the accumulated plastic strain was high due to the irreversibility of strain accumulation with the increase of deformation. After 9 turns deformation, the grain refinement become obvious and the volume percentage of LAGBs reaches steady state, as shown in Fig.…”

Systematic experimental studies on microstructure evolution and texture development of pure Al during torsion at room temperature are carried out by electron back scattering diffraction (EBSD) and transmission electron microscopy (TEM). The microstructure evolution states the grains of deformed pure Al are refined evidently. The refinement mechanisms of pure Al are attributed to dislocation slip and recrystallization. The texture evolution of pure Al indicates that the position of {001} fiber changes slightly, but its intensity first increases and then decreases with the increase of deformation during torsion. Finally, the processes of grain refinement of pure Al during torsion are discussed based on TEM observations.

“…Furthermore, Zirconium addition to RE elements has been shown to improve the mechanical properties due to grain refinement. [4,5] Some studies revealed that the dynamically recrystallized (DRX) grain size of wrought magnesium alloy was lower than that of as-cast magnesium alloy. In addition, the increasing rate of dynamic recrystallization in the as-cast material was considerably lower than the dynamic recrystallization in the wrought material.…”

In this paper, magnesium ZE41A alloy plates were butt joined through friction stir welding (FSW) and Tungsten Inert Gas welding processes. Process-induced microstructures were investigated by optical and SEM observations, EDX microanalysis and microhardness measurements. The effect of a post-welded T5 heat treatment on FSW joints was also assessed. Sound joints were produced by means of both techniques. Different elemental distributions and grain sizes were found, whereas microhardness profiles reflect microstructural changes. Post-welding heat treatment did not induce significant alterations in elemental distribution. The FSW-treated joint showed a more homogeneous hardness profile than the as-welded FSW joint
