Abstract Metals and ceramics have contrasting limitations—metals exhibit lower strength and poor high-temperature stability, whereas ceramics are inherently brittle. Materials combining high strength, fracture toughness and thermal stability remain an important scientific objective. Here we report Re–Co–Ta–B bulk metallic glasses (BMGs) that overcome this fundamental limitation, achieving a remarkable fracture strength of about 6.43 GPa while maintaining around 30 MPa m1/2 fracture toughness.
