Abstract

Novel, pentabasic Ti-Cu-Ni-Zr-Hf bulk metallic glasses (BMGs), with critical diameters of 2-4mm, were successfully developed through the proportional mixing of the binary eutectic compositions of Ti₂₇Cu₇₃, Ti₇₆Ni₂₄, Zr₇₆Ni₂₄ and Hf₈₄Ni₁₆. According to the concept of binary eutectic units, five Ti-Cu-Ni-Zr-Hf BMGs were fabricated, of which the Ti_29.44Cu_46.72Ni_7.88Zr_7.6Hf_8.4 alloy had the lower glass forming ability, and the smallest reduced ideal glass transition temperature δ and δCpm/δSm values, where δCpm and δS_m represent the specific heat and entropy differences at the melting temperature (T_m), respectively. The Ti_29.44Cu_46.72Ni_7.88Zr_7.6Hf_8.4 alloy also showed good mechanical properties, i.e., good plastic strain and relatively high compressive strength.
