High-pressure effects on Ti–Zr–Ni metallic glass and its corresponding quasicrystal

The room-temperature high-pressure effects on Ti38Zr38Ni24 metallic glass and its corresponding icosahedral quasicrystal have been investigated by in-situ angle-dispersive synchrotron radiation. It is demonstrated that the thermodynamic metastable metallic glass and icosahedral quasicrystal retain their structures up to 42.9 and 46.0 GPa, respectively. For the Ti38Zr38Ni24 quasicrystal, disorders are likely developed during compression. However, no special behaviors are detected in its amorphous counterpart although thermal analyses suggest that the metallic glass is possibly in microquasicrystalline nature.
