| Summary: | The relationship between vein-like patterns and plasticity was investigated in Ti29.44Cu46.72Ni7.88Zr7.6Hf8.4 and Ti31.4Cu43.8Ni8.8Zr7.6Hf8.4 bulk metallic glasses. By observing the fracture morphology of the samples using a phenom scanning electron microscope (PSEM), we demonstrated that a large or small plasticity results in a large or small average height of “projection” in the vein-like patterns, respectively. The results indicate that, if the height of “projection” in the vein-like pattern is large or small, the absorptive plastic work is also large or small, in turn indicating that the plasticity of the corresponding metallic glasses is large or small, respectively. The height of “projection” in the vein-like pattern was determined to reveal the degree of plasticity in Ti-Cu-Ni-Zr-Hf metallic glasses.
