In this study, we have proposed to use binary eutectics, rather than individual constituent elements, as basic units for designing complex multi-component bulk metallic glasses (BMGs), based on a novel physical concept of “ideal” glass-forming liquids. An innovative approach to designing multi-component BMGs in these ideal liquids was thus established and the reliability and usefulness of the current approach of this strategy has been confirmed in the Zr-Fe-Cu-Al metallic systems. As a result, several new BMGs with superior GFA in this system were successfully developed.
