摘要：

Temperature dependencies of the shear viscosity of a Finemet glassy alloy under the heating rates ranging from 0.3 to 100 K/min are obtained. It is shown that isothermal cuts of these dependencies give linear viscosity increase with the inverse heating rate that accords with the flow equation derived within the framework of the directional structural relaxation model.
