Role of initial texture on the plastic anisotropy of Mg–3Al–1Zn alloy at various temperatures

Effect of Initial Texture on Rollability of Mg-3Al-1Zn Alloy Sheet

“…When the loading direction is normal to the c-axis of HCP lattice (sample A), {1012} twinning can be easily activated by plastic deformation [23]. By contrast, primary twinning is difficult to be activated in sample B at small reduction.…”

“…Research also found that rollability of AZ31 was affected by texture during warm rolling at 150 °C, and those with special texture can be deformed up to 44% reduction without cracking attributed to the activity of prism (a) slip [8]. Effects of initial texture on dynamic recrystallization [9], plastic anisotropy [10], microstructure, and formability [11] of Mg-3Al-lZn alloy were studied by using uniaxial compression tests. When the loading direction is close to the c-axis of the HCP lattice, the flow stress is higher than that perpendicular to c-axis, which gives better ductility [12,13].…”

Twinning characteristic in tension of magnesium alloys and its effect on mechanical properties

“…However, when extension was loaded along the c-axis, all the six twin variants would be preferred, and therefore, crossed twin patterns were likely formed [5,18]. The different activation mode of twinning could significantly affect the strain hardening behavior and material performance [19,20].…”

Anisotropy of flow during isothermal forging of rolled AZ31B magnesium alloy rolled plate in three orthogonal directions: Correlation with processing maps

“…Microstructural observations revealed [16] that hot deformation in the strain rate range of 0.1-1.0 s À 1 , referred as the ''bifurcation'' region, causes unusual grain growth. Lee et al [14] and Rao et al [17] observed that the shape of the rolled material deformed parallel to the rolling direction exhibited elliptical shape due to the initial texture. Wang et al [12] reported that the initial texture in the rolled plate retarded DRX when deformed in the rolling direction compared to the normal direction.…”

“…An important microstructural change that occurs during mechanical processing of AZ31 is the development of texture which has a significant influence on the mechanical properties and workability of the alloy [10][11][12][13][14][15]. The evolution of texture and grain size in hot extrusion [15] and differential speed rolling of AZ31 [13] have been correlated with the process parameters.…”
