Novel nanostructure consisting of the metastable nanocrystalline particles embedded in the glassy matrix are reported in the rapidly quenched Cu 60 (Zr or Hf) 30 Ti 10 alloys. The transformation behavior and mechanical properties in the nanoscale composite alloys are also investigated. The as‐cast bulk sample of Cu 60 Zr 30 Ti 10 alloy exhibits the high fracture strength of approximately 2000 MPa in the compressive test at room temperature.
