A new Fe‐based bulk glassy alloy with high glass‐forming ability, super‐high fracture strength, and plasticity is described. The [(Fe 0.8 Co 0.1 Ni 0.1 ) 0.75 B 0.2 Si 0.05 ] 96 Nb 4 alloy has a super‐high strength of over 4000 MPa, the highest yet reported for Fe‐based bulk alloys. In compressive failure, a shear band with an angle of 43° relative to the compression direction can be observed by scanning electron microscopy (see Figure).
