Abstract
The tensile deformation behavior of Ti50Zr20Nb12Cu5Be13 bulk metallic glass composite at ambient temperature was investigated by uniaxial tensile tests All stressstrain curves of Ti50Zr20Nb12Cu5Be13 demonstrated work hardening and work softening during deformation Many shear bands were generated during deformation In parallel the dendrite of Ti50Zr20Nb12Cu5Be13 underwent severe plastic deformation Shear bands turned into microcracks during tensile deformation By observing the fracture surface the fractograph showed only a ductile dimple fracture pattern Therefore the excellent plasticity of the Ti50Zr20Nb12Cu5Be13 bulk metallic glass composite was due to the formation of plastic dimple fracture and many shear bands during tensile deformationThis work was supported by the Fundamental Research Fund of Northwestern Polytechnical University JC20120203 Specialized Research Fund for the Doctoral Program of Higher Education 2013610212007 and Program of Introducing Talents of Discipline to Universities B08040
