“…At present, the asymmetric rolling (ASR) was used to process the magnesium alloy sheet with rotating the basal plane away from the rolling plane. Several investigations into the microstructure of and texture evolution in magnesium alloys processed by asymmetric rolling can be found in the literature [12,[14][15][16][17][18][19][20]. The Mg-3Al-1Zn alloy sheets with a tilted basal texture were obtained by asymmetric rolling and compared with a normal symmetrically rolled sheet, the ASR-processed sheet showed a larger uniform elongation.…”

“…The third way to improve the mechanical behaviour of Mg alloys is based on modifying the texture, which has an important influence on the ductility and on the plastic anisotropy [31][32][33][34][35][36][37][38][39][40][41][42]. Depending on the processing route followed, different types of textures are obtained.…”

“…During extrusion, the c-axes align perpendicular to the extrusion direction. Considerable efforts have been devoted to develop novel textures by innovative processing techniques such as asymmetric rolling [40][41][42]. If a tensile test is carried out in a rolled Mg sheet along an in-plane direction, basal slip becomes difficult and non-basal deformation modes become active.…”

The work carried out by the authors over the last decade on the processing, microstructural characterization and the mechanical behaviour of Mg alloys is reviewed. In particular, the potential for grain refinement and for the development of specific textures of large strain hot rolling (LSHR), equal channel angular pressing (ECAP) and accumulative roll bonding (ARB) is discussed. The recrystallization and the deformation mechanisms predominant in Mg alloys are analysed as a function of the grain size and the texture in a wide range of stresses, strain rates and temperatures. Finally, the feasibility of superplastic forming of Mg alloys was examined, taking into account the influence of factors such as grain size stability and microstructural heterogeneities.K e y w o r d s : magnesium alloys,

“…Recently, several techniques have been used to refine the microstructures in magnesium alloys, including equal channel angular extrusion (ECAE), accumulative roll-bonding (ARB), normal rolling and different speed rolling (DSR), etc. [3][4][5][6][7]. All of these methods were successful in achieving the refined grain structure and excellent mechanical properties due to the shear deformation.…”

Equivalent strain and redundant shear strain distribution in the roll bite during normal rolling were calculated by a numerical integration method combined with the experimental method. The microstructural parameters, such as length of high-angle grain boundaries (HAGB), length of low-angle grain boundaries (LAGB) per unit area, and (0002) basal texture in surface layer and center layer were measured quantitatively by EBSD or X-ray diffraction. The effect of equivalent strain and redundant shear strain on the microstructure and (0002) basal texture evolution in AZ31 alloy during hot rolling were examined. As a result, it was found that the formation of the HAGB depends on the equivalent strain, while the formation of the LAGB is strongly affected by the redundant shear strain, which restrains the formation of the LAGB. The experimental results also suggest that the redundant shear may have little effect on improving DRX and weakening the (0002) basal texture intensity when the redundant shear strain is in small to moderate range (B0.8).
