The ductility of magnesium is intimately related to dislocation. Understanding the behavior of dislocations is of critical importance for resolving the mechanical properties and for alloy design. By using in situ TEM mechanical testing of pillars of pure Mg single crystal, we found that dislocation can accommodate considerable plasticity. Our findings provide information on the mobility of dislocation and its relationship with plasticity of submicron-sized pure Mg. The experimental strategy can be extended to understanding the dislocation behaviors in other hexagonal metals.
