Dislocation engineering concept has been successfully employed to tackle the strength-ductility trade-off in steels, resulting in the development of high-strength high-ductility deformed and partitioned (D&P) steel. The present perspective proposes to employ such dislocation engineering concept to develop strong and ductile magnesium (Mg) alloys. High density of < c + a > dislocations could be generated at appropriate temperature and retained in the Mg alloy after quenching to room temperature. Those < c + a > dislocations inherited from the warm deformation could provide < c + a > dislocation sources when the Mg alloy is deformed at room temperature, resulting in good ductility. The high dislocation density generated at warm deformation provides dislocation forest hardening, leading to improved yield strength of Mg alloy.
