Zr-based bulk metallic glass composites have been fabricated by a water-cold copper mold.The instinct nature of amorphous and the amount of crystalline phases are determined by X-ray diffraction (XRD).Differential scanning calorimetry (DSC) is employed to investigate the thermal stability.The uniaxial compressive tests are performed under quasi-static loading at room temperature.Shear band propagation during compressive are captured with the high-speed camera.Fracture surface of compressive deformation specimens are analyzed by scanning-electron microscopy (SEM).The results show that the volume fraction of crystalline phase is about 20% in the metallic glass matrix.Intermetallic compounds as the second crystalline phase separate from the metallic glass matrix during solidification.The bulk metallic glass composite exhibits high fracture strength between 1500 to 1800 MPa and essential no plastic responce.The emission of sparks lasting for tens of microseconds are observed, revealing a large heat content generated within the shear band.Dimple-like pattern, vein-pattern and micro-cracks of fracture surface are obtained after compressive deformation.The micro-cracks caused during deformation mainly attribute to the intermetallic compounds.Stress concentration of the existing second phase induce micro-cracks and then generate several fragments.The limit ductility due to the brittleness of intermetallic compounds.It is expected that enhanced ductility of bulk metallic glass composite with the suitable second phase as potential structure functional material.
