SCALING OF VISCOSITIES OF GLASS-FORMING ALLOYS

The viscosity of molten Ni80P20 was measured from 1143 to 1253 K by th e capillary flow method. It can be described very well by the Vogel-Fu lcher equation. When the viscosity is expressed in a reduced temperatu re scale which is defined as T/T(g) where T(g) is its glass transition temperature, it follows the principle of corresponding states, the sa me as other easy glass forming systems.
