The glass formation behavior was investigated in the melt spun Zr-Ti-Cu-Ni-X (X=B, P and Si) ribbons. The magnitude of supercooled liquid region of Zr-Ti-Cu-Ni alloy increased with an addition of alloying element. The glass transition temperature and the crystallization temperature increased and the magnitude of supercooled liquid region decreased with increasing the content of alloying elements. The largest supercooled liquid region was observed in the Si containing alloy. This is believed to be due to the dense atom packing with the optimum atomic size ratio of constituent elements.
