Abstract

For a warm rolled Mg-Zn-MM (Misch Metal) alloy sheet, the static recrystallization process is adapted to develop a weak-textured microstructure with an average grain size of 4. μm. Due to the relatively low recrystallization temperature of the alloy, the sheet can be fabricated by the warm rolling process and then recrystallized at 220. °C. Enhanced ductility is observed from room temperature to 350. °C. In addition to the basal slips within the grains, at room temperature nano-twins actively form near the grain boundaries, accommodating the plastic strain incompatibility near the grain boundaries. Moreover, above 150. °C, dynamic recrystallized grains are actively developed during deformation. In the temperature range of 100-350. °C, the values of elongation to failure are approximately 40% higher than those of the AZ31 alloy sheet without the loss of tensile strength.
