“…The double-peak texture of (0002) plane has been reported in the other studies. 18,19) It is noted that the texture intensities of the route 2, route 3 and route 4 specimens were weaker than that of the route 1 specimen, and in particular, the texture intensities of the route 3 and route 4 specimens were approximately half of that of the route 1 specimen. The fact that the route 2, route 3 and route 4 specimens showed lower texture intensities than the route 1 specimen is probably related to the deference in plastic flow during rolling, as shown in Fig.…”

Microstructure, tensile properties and press formability of AZ31 Mg alloy sheets processed by unidirectional rolling, reverse rolling and cross rolling were investigated. The intensity in (0002) plane texture for the reverse-rolled and the cross-rolled specimens was lower than that for the unidirectional-rolled specimen. In addition, the Erichsen values of the formers were larger than those of the latter. The superior press formability for the formers could not be explained from the viewpoint of the elongation to failure, n-value, average r-value and planar anisotropy of the r-value, but it was related to a reduction in directional dependence of the thickness-direction strain and width-direction strain normalized by the tensile-direction strain (" t =" L and " w =" L ). Therefore, it is suggested that the minor texture formation due to reverse rolling and cross rolling gives rise to the reduction in anisotropy of strain, resulting in the superior press formability for the reverse-rolled and cross-rolled specimens.

“…The texture of the fraction of deformed grains forms a basal alignment parallel to the sheet plane, as well as a TD spread. This is associated with a six-peak symmetry of the prismatic planes, which is often associated with prismatic slip [24] along similar strain paths. The latter feature is also developed after deformation with geometry VII; however, the TD spread does not appear.…”

Abstract:As a generalized semi-finished product, the use of magnesium sheets requires addressing two major aspects of their processing: their microstructure and texture control, which are both essential for the forming behavior of such sheets during their forming to parts. Further, the processing of such sheets is complex, and therefore expensive, and requires simplification. In this work, magnesium alloys AZ31, ZE10, and ME21 are investigated in the form of conventionally rolled sheets, as well as in the form of extruded sheets. Their microstructural and textural development are correlated to their mechanical and forming properties. During extrusion, strong textures develop that hinder stretch-forming operations, even in rare earth-containing alloys. Chemical composition and process parameters have a significant impact on the texture development, and enable the design of sheet materials with weak textures and potentially enhanced formability.
