“…values were observed for the three sheets prepared according to different rolling parameters. Some studies have shown that the formability of a sheet is strongly dependent on its microstructure, texture, and plastic deformation mechanism during stretch forming [ 17 , 27 ]. Therefore, in this study, it was necessary to systematically investigate the three sheets’ microstructures and texture evolution as well as their plastic deformation mechanisms during stretch forming.…”

“…In addition, Shi et al investigated the effect of different final-pass rolling reduction methods on the microstructure and properties of Mg–1.1Zn–0.76Y–0.56Zr alloy, finding that increasing the final-pass rolling reduction can modify the TD-split texture, achieving the reduction of planar anisotropy. When they increased the final-pass rolling reduction from 30% to 70%, the Erichsen value increased from 7.0 mm to 8.0 mm [ 16 , 17 ]. The reasons for the weakening of texture by thermomechanical processing are complex.…”

In this work, Mg–2Zn–0.5Ca (wt.%) alloy sheets fabricated according to various rolling parameters were evaluated to investigate the effect of rolling parameters on room-temperature stretch formability. The sheet rolled at 360 °C with a pass rolling reduction of 10~33% exhibited the worst I.E. value of 4.4 mm, while the sheet rolled at 360 °C with a pass rolling reduction of 20~50% exhibited the best index Erichsen (I.E.) value of 5.9 mm. Among the sheets, the (0002) basal texture intensity was the weakest, and the grain basal poles split away from the normal direction toward both the rolling direction and the transverse direction. Microstructural and deformation mechanism measurements of stretch forming to 2 mm for the sheet rolled at 360 °C with a pass rolling reduction of 20~50% by electron backscatter diffraction and in-grain misorientation axes showed that there was a higher activity of {10–12} extension twins and that a prismatic <a> slip was initiated. As a result, the weakening of the texture and the broader distribution of basal poles in the plane contributed to the improved formability of the sheet rolled at 360 °C with a pass rolling reduction of 20~50%.

“…What's more, annealing process is also an effective way to modify the microstructure and texture [27,28]. The ZWK100 alloy can form a weak texture and achieve low planar anisotropy by final-pass heavy reduction rolling and subsequent annealing [29]. The double-peak texture tilted to RD of multi-pass hotrolled AZMX1100 alloy can transform into an elliptical annular texture at low annealing temperatures while a uniform weak elliptical annular texture at high annealing temperature of 400 °C [30].…”

The unidirectional rolled Mg-Zn-Gd sheet usually exhibited non-basal texture with two peaks whose tilting angle were about 42° from normal direction to transverse direction (TD), which would cause the mechanical anisotropy. In this study, multi-cross rolling followed by annealing was used to tailor the texture and mechanical anisotropy for Mg-Zn-Gd alloy. With increasing annealing temperature, the rolled basal texture with two peaks gradually transformed into the circle texture with multi-peaks. In order to figure out different texture components evolution during annealing, the basal texture, R-texture and T-texture component were defined and studied. The results showed that the change of R-texture and T-texture component was asynchronous with increasing annealing temperature from 250 to 400 °C. The tilting angle of R-texture component increased slightly, while the tilting angle of T-texture component increased obviously, and this phenomenon was attributed to the preferential nucleation at grain nucleation stage rather than preferential grain growth. The yield strength along TD was more sensitive to annealing temperature compared with that along rolling direction (RD), resulting in different descending slopes and yield strength anisotropy with increasing annealing temperature. Annealing at 300 °C was the best annealing temperature due to low yield strength anisotropy, moderate strength and good elongation among these annealing temperatures. The Schmid factor for basal slip indicated that the activity of basal slip along RD increased slightly, while that along TD increased obviously with increasing annealing temperature from 250 to 400 °C, which should be caused by the asynchronous change of R-texture component and T-texture component, consequently resulting in the transformation from isotropic yield strength to anisotropic yield strength.
