Surface mechanical attrition-induced hierarchical gradient nanostructuring enables ultrahigh strength and moderate ductility in Mg-Sn-Zn-Zr alloys

The engineering application of lightweight structural magnesium (Mg) alloys is usually impeded by the challenge of achieving high strength together with useful tensile ductility. In this study, rare-earth-free Mg-6Sn-3Zn-0.3Zr alloys with ultimate tensile strengths (UTS) of 385–4...
