摘要: Abstract An ultra-high strength Mg-3Al-Zn alloy with low tension-compression yield asymmetry was successfully fabricated through adding 0.2 wt% MgO. The as-extruded exhibits a tensile stress of 459 MPa, an ultimate 519 MPa, elongation to failure 3.2%, and 1.01. combined effect partially nanocrystallized structure, nanoscale coherent MgO precipitates, ultra-fine recrystallized Mg grains results in the further additional weak basal texture.
