High strength and ductility in a rare-earth free magnesium alloy processed by rotary swaging and flash annealing
Magnesium (Mg) is the lightest structural metal. It is promising for aerospace applications if its mechanical properties can be improved at a reaso…
Suppressed ballistic transport of dislocations at strain rates up to 109 s–1 in a stable nanocrystalline alloy
Dislocations are crucial to plastic deformation in crystals. At extreme strain rates, their motion shifts from thermally activated glide to ballist…
Revealing the mechanism of cold metal transfer
Cold metal transfer (CMT) is a pioneering feeding system widely used in wire-arc additive manufacturing (WAAM) and welding. However, process optimi…
