Abstract

The effect of liquid ejection temperature (T_liq) during melt-spinning on the thermal stability and crystallization behavior of amorphous Ni₅₉Zr₂₀Ti₁₆Si_5-xSn_x (x=0,3) alloys has been studied. Glass transition temperature (T_g) and crystallization onset temperature (T_x) of the amorphous Ni₅₉Zr₂₀Ti₁₆Si₅ alloy are not affected by the variation of T_liq. On the other hand, the amorphous Ni₅₉Zr₂₀Ti₁₆Si₂Sn₃ alloy shows different behaviors. T_g is not dependent on T_liq but T_x shifts towards the lower temperature side with decreasing T_liq, resulting in a decrease of the supercooled liquid region (δT_x=T_x-T_g). The effect of T_liq on the thermal properties can be understood by the presence of short-range order clusters, which is related to Ni-Zr atomic pairs in the liquid state.
