Tailoring the texture of an extruded Mg sheet through constrained groove pressing for achieving low mechanical anisotropy and high yield strength

• Constrained groove pressing (CGP) was utilized to modify the texture and mechanical properties of extruded Mg-2Gd-3Zn sheet with typical TD (transverse direction)-split texture and pronounced mechanical anisotropy. The texture evolution sequence during CGP was studied and it was observed that a new (1211) component with basal poles rotated 15-30 toward the extrusion direction (ED) is introduced during CGP, as a result of simultaneous activation of basal and prismatic slip and shear deformation. Finally, a non-basal ED-TD double split texture was obtained after the CGP process, resulting in significantly reduced mechanical anisotropy.
