%X The dynamic viscosity and the steady-state viscosity are measured for the metallic glass Ni30Zr70. The dynamic viscosity increases linearly with the decrease of the heating rate as a result of the structural relaxation, and the temperature dependence of the dynamic viscosity can be described by the Arrhenius equation in the temperature range below Tg. The temperature dependence of the steady-state viscosity satisfies the Fulcher-Vogel equation at temperatures below Tg. From the high temperature at temperature of the onset of crystallization dynamic viscosity values with four heating rates, the equilibrium viscosity is determined. Over the temperature range of 63C to 670K, the temperature dependence of the equilibrium viscosity is well described by the Fulcher-Vogel equation.
