“…Development of Ti-based bulk glassy alloys is expected to significantly expand the application fields of bulk glassy alloys. To date, a number of Ti-based bulk glassforming alloys, such as Ti-Cu-Ni-(Sn or Sb) [8], Ti-Cu-Ni-Si-B [9,10], Ti-Zr-Ni-Cu-Sn [11], Ti-Cu-Ni-Zr-Al-Si-B [12], (Ti, Zr)-(Cu, Ni) [13] have been synthesized by the copper mold casting method. Ti-based bulk glassy alloys were considered for biomedical applications due to their unique mechanical properties (lower Young's moduli, higher hardness and larger elastic limitation) and good biocompatibility.…”
