Enhanced ductility in strongly textured magnesium produced by equal channel angular processing

Equal channel angular processing is shown to induce a strong deformation texture, which persists after recrystallization. The enhancement in the tensile ductility along the extrusion axis originally reported by Mukai et al. [Scripta Mater 45 (2001) 89] is discussed in terms of magnesium’s deformatio...

Zusammenfassung:Equal channel angular processing is shown to induce a strong deformation texture, which persists after recrystallization. The enhancement in the tensile ductility along the extrusion axis originally reported by Mukai et al. [Scripta Mater 45 (2001) 89] is discussed in terms of magnesium’s deformation mechanisms, plastic anisotropy, and the texture itself.
