“…Thus, it can be inferred that the difference in the microstructures of AZ31 alloy after rolling may be due to the variety of the thickness reduction at a single rolling pass. Zhu et al [19] reported that both of the twinning and DRX were the main mechanisms that consumed strain energy during the deformation. But it was reported that the critical strain for twinning was lower than that for DRX [19].…”

“…Zhu et al [19] reported that both of the twinning and DRX were the main mechanisms that consumed strain energy during the deformation. But it was reported that the critical strain for twinning was lower than that for DRX [19]. As the strain during the deformation is not attained to the critical strain for DRX but for twinning, the twinning is activated, which leads to the release of strain energy, resulted in the suppression of the DRX.…”

“…Rollability and formability of rolled sheets Some attempts have been made to increase the plate thickness reduction per pass by changing the rolling speed. [211][212][213][214][215] This is because a larger thickness reduction per pass and/or a higher rolling speed can reduce the processing cost. This approach is worth exploring especially when a lower-cost sheet is made without sacrificing useful formability and mechanical properties.…”

Pure magnesium (Mg) develops a strong basal texture after conventional processing of hot rolling or extrusion. Consequently, it exhibits anisotropic mechanical properties and is difficult to form at room temperature. Adding appropriate alloying elements can weaken the basal texture or even change it, but the improvement in formability and mechanical properties is still far from expectations. Over the past 20 years, considerable efforts have been made and significant progress has been made on wrought Mg alloys at the fundamental and technological levels. At the fundamental level, textures formed in sheets and extrusions of different alloy compositions and produced under different strain paths or thermomechanical processing conditions are relatively well established, with the assistance of the advanced characterization technique of electron backscatter diffraction. At the technological level, room temperature formability of sheet has been significantly improved, and tension-compression yield asymmetry of extrusion is also remarkably reduced or eliminated. This paper starts with an overview of dislocations, stacking faults and twins, and deformation of single crystals of pure Mg along different orientations and under different loading conditions, followed by a review of microstructure (texture and grain size) and deformation of polycrystalline pure Mg with different textures, grain sizes, and loading conditions. With this information as a base, texture, grain size, and deformation of polycrystalline Mg alloy sheets and extrusions produced under different processing conditions are systematically examined and compared. Remaining and emerging scientific and technology issues are then highlighted and discussed in the context of texture and grain size. The need for better-resolution diffraction and spectroscopy techniques is also discussed in the relationship between texture change and grain boundary solute segregation.

“…Currently much effort is being put into the high-speed processing methods, such as high-speed extrusion [1,2], high strain-rate rolling [3,4] and high strain-rate forging [5][6][7][8], etc., in attempts to lower the processing cost while still retaining good mechanical properties of wrought Mg alloys. In our previous study [5], multi-directional impact forging (MDIF) with high strain rate was successfully used to fabricate the bulk AZ61 Mg materials with fine grains and non-basal texture, and consequently, enhanced strength and ductility, demonstrating that it was a highly efficient approach to enhance mechanical properties and lower cost.…”
