Changes of the texture and the mechanical properties of the extruded Mg alloy ME21 as a function of the process parameters

▶ Ductility enhancement of the wrought magnesium alloy ME21 compared to the typical magnesium alloy AZ31. ▶ The “rare earth effect” and particle-stimulated nucleation during recrystallization results in a fine-grained microstructure with an almost randomized crystallographic texture for all conventional indirect extruded products. ▶ The variation of the extrusion parameters billet temperatures, press ratio and the cooling conditions allows the variation of the texture so enabling intermediate strength or enhanced ductility.
