Significant disparity of non-basal dislocation activities in hot-rolled highly-textured Mg and Mg-3Al-1Zn alloy under tension
It is well-established that Mg-3Al-1Zn (AZ31) alloy exhibits much better tensile ductility than
pure Mg. However, the underlying mechanisms for such difference still remain relatively …
