Аннотация:The temperature dependences of kinematic viscosity of glass-forming melts Fe80Si6B14, Fe77Si8B15, Fe78Ni1Si9B12, Fe78.5Ni1Mo0.5Si6B14, and Fe73.6Nb2.4Cu1Si15.8N7.2 within the interval of temperatures 1200-1600degreesC during the heating and cooling schedules are investigated. In polytherms, the anomalies such as a sharp decrease of viscosity at a heating schedule and its hysteresis at the subsequent cooling are revealed. The revealed anomalies of viscosity are explained within the framework of the theory of the long-wave fluctuations of density in glass-forming melts.
