Abstract

The Ti-Zr-Cu-Pd-Sn bulk metallic glasses have some advantages of high yield strength about 2000Mpa, good corrosion resistance and absence of toxic element, such as Al, Ni and Be. So the Ti-based metallic glass is regarded as a promising biomaterial and lightweight material. The homogenous deformation and superplastic forming process of Ti-Zr-Cu-Pd-Sn-Sn bulk metallic glass was investigated. The homogeneous deformation behavior is strongly dependent on the strain rate. The metallic glass exhibits Newtonian behavior at relative low strain rate and non-Newtonian behavior at relative high strain rate. The micro-gear was successfully extruded by superplastic forming process, indicating that the Ti-Zr-Cu-Pd-Sn bulk metallic glass processes good workability in supercooled liquid region. The deformed metallic glass was investigated by X-ray diffraction (XRD), demonstrating that no detectable crystalline phase precipitated during superplastic forming.
