Influence of initial texture on rolling and annealing textures of Mg–3Al–1Zn alloy sheets processed by high temperature rolling

Effect of the final rolling speeds on the stretch formability of AZ31 alloy sheet rolled at a high temperature

“…With increasing the rolling speed from 0.1 m/s to 0.4 m/s, the texture intensity of the as-annealed sheets was decreased from 4.4 to 3.1, and the texture distribution was more random. It was reported that the SRX behaviour of the sheet during annealing could be influenced by the dislocation slip, grain boundary slip (GBS) and twinning [22,23], which leaded to the variety of the texture characteristics of the sheet. Huang et al [9] suggested that the rotation of nuclei and small SRXed grains in various directions during annealing may be promoted by the absorption of non-basal dislocations in boundaries, which leaded to a remarkable weakened texture.…”

Modeling Twin Clustering and Strain Localization in Hexagonal Close-Packed Metals

“…This is mainly attributed to the very strong basal textures that normally develop in Mg during most industrial rolling procedures [3][4][5] and the low number of easily activated slip systems at room temperature. [6][7][8][9][10][11][12] Plastic deformation in the thickness direction of such strong textured sheets would require the activation of hc+ai slip; however, the critical resolved shear stress (CRSS) values for such slip modes are relatively high at room temperature. A lot of recent work has been focused on designing alloys or rolling techniques that produce weaker textures to improve stretch formability.…”

“…A lot of recent work has been focused on designing alloys or rolling techniques that produce weaker textures to improve stretch formability. [3][4][5][6][7][8][9][10][11][12] However, the mechanisms by which strong textured magnesium sheets fail are not very well understood. Also the exact role of the various slip modes that may affect formability, i.e., an explanation of the considerable difference between the stretch formabilities of various hcp metals is not known.…”

Texture evolution of AZ31 magnesium alloy sheets during warm rolling

“…Huang et al [25] studied the influence of different amounts of reduction per pass on the microstructure and texture of an AZ31 Mg alloy via differential speed rolling at the same total amount of reduction, and observed that the inclination direction of the basal pole with respect to the RD depended on the amount of reduction per pass. They also examined the effects of initial texture on rolling and annealing texture of AZ31 Mg alloy rolled at different temperatures [26]. Li et al [27] studied the microstructure and texture evolution of ME20 magnesium alloy during hot rolling and compared with those of AZ31 magnesium alloy.…”
