Title	CityU develops the world’s strongest magnesium alloy
Description	Professor Lu’s group is working hard on developing structural and functional materials with high strength and high ductility to overcome the limitations of existing materials. In the past five years, the team successfully developed the supra-nano-dual-phase glass-crystal alloy film structure. This material has a dual phase structure smaller than 10nm, which the research group named supra-nano-dual-phase glass-crystal (SNDP-GC). Supra-nano means that the size of each phase is less than 10nm, and glass is in the general amorphous phase. This is a new family of alloy structures – a world first.
