Pure magnesium exhibits poor ductility owing to pyramidal〈 c+ a〉 dislocation transformations to immobile structures, making this lowest-density structural metal unusable …
Magnesium is a lightweight structural metal but it exhibits low ductility—connected with unusual, mechanistically unexplained, dislocation and plasticity phenomena—which makes …

Magnesium, the lightest structural metal, usually exhibits limited ambient plasticity when compressed along its crystallographic c-axis (the “hard” orientation of magnesium). Here we …
Alloying magnesium (Mg) with rare earth elements such as yttrium (Y) has been reported to activate the pyramidal< c+ a> slip systems and improve the plasticity of Mg at room …
Temperature effects on the mobility of< c+ a> dislocations on pyramidal planes are characterized by molecular dynamics simulations. On the first-order pyramidal planes, near …

Plasticity in magnesium crystals oriented for c-axis compression has been usually attributed to< c+a> dislocation slip on second-order pyramidal {11 2¯ 2} planes. Through molecular …
We have recently reported that a high strain-rate rolling process is effective for producing strong and ductile Mg alloy sheets. Here we elucidate the fundamental mechanisms that are …
