Abstract
The tensile deformation behavior of Ti50Zr20Nb12Cu5Be13 bulk metallic glass composite at ambient temperature was investigated by uniaxial tensile tests. All stress-strain 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 deformation.
