Bulk Metallic Glass Composites with Transformation‐Mediated Work‐Hardening and Ductility

A bulk metallic glass (BMG) composite with large tensile ductility and work-hardening capability (see figure) was developed by applying the "transformation-induced plasticity" concept to amorphous alloys. The current approach is not believed to be limited to the current BMG composite but could promote ductility in other BMG systems, offering a new paradigm for developing BMGs with improved ductility as practical engineering materials.
