抄録

New bulk metallic glasses exhibiting a high glass forming ability were formed by a substitution of Hf and Nb for Zr and Ti in quaternary Cu-Ni-Zr-Ti system. An 8 mm-diameter BMG rod was obtained at the Cu<SUB>50</SUB>Ni<SUB>8</SUB>Zr<SUB>15</SUB>Hf<SUB>3</SUB>Ti<SUB>23</SUB>Nb<SUB>1</SUB> composition by suction casting method. The glass transition temperature, crystallization temperature and reduced glass transition temperature of the BMG were 699 K, 754 K, and 0.59, respectively. Making an alloy system more complex was useful to increase the GFA.
