CityUHK creates novel metallic glass with dual-high strength and ductility

Description

City University of Hong Kong (CityUHK) has recently developed a new multi-principal element metallic glass that shatters previous limitations of tensile ductility. This novel glass is twice as ductile as traditional metallic glasses, and its strength nearly doubles when stretched. The key to this extraordinary property lies in the unique structural evolution of the glass during deformation, which causes it to harden rather than soften, making it significantly more resistant to sudden breakage under tension. The findings surpass limitations of tensile ductility in metallic glasses and provide a promising pathway to create strong and ductile glasses.
