摘要：

An extruded WE43 magnesium alloy (WE43-EX) consisting of fine-grained micro structure exhibits sufficient ductility under dynamic loading. The high ductility of the extruded alloy is owing to the transition in the fracture mechanisms from intergranular fracture to transgranular one with grain refinement. It is especially noted that the absorption energy per weight in WE43-EX is twice higher than that of high strength aluminum alloys. It should be expected that the alloy exhibits the high speed impact performance during foreign object damage.
