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.
