Low-density magnesium alloys are a promising type of material for making lighter vehicles and improving fuel efficiency. One challenge for lightweighting is developing high-strength magnesium alloys. Wu et al. created a dual-phase magnesium thin film with near-ideal strength. The alloy consists of small nanocrystalline cores surrounded by glass, combining the benefits of both phases to create the high-strength alloy. The strategy for creating this type of nanostructure should translate to other types of alloys, opening a different pathway to creating high-strength metals.
