Ni-Nb-Ti-Zr amorphous alloys were manufactured using melt-spinning methods. Amorphous formability, the supercooled liquid region before crystallization and mechanical properties were examined. The value of the reduced glass transition temperature and the supercooled liquid region of Ni_62Nb_10Ti_13Zr_15 alloy were relatively high and were 0.612 and 76 K respectively. However, amorphous bulk alloy rod was not formed using the Cu-mold die casting, The mechanical properties were in the range of 800∼900DPN of hardness and 2.5∼2.8 GPa of tensile strength in the whole composition range.
