Abstract: The method of crucible rotating oscillation damping was employed to measure the kinematic viscosity of aluminum melt, and the curve of viscosity v versus temperature T from 935 to 1383 K was obtained. Besides, based on the calculation model of the evolution behavior of atomic clusters in liquid structure, the curve of atomic clusters size d versus temperature was obtained, and the calculated results are in good agreement with the experimental values. By analyzing experimental data, it was found that both the viscosity and the size of atomic clusters of aluminum melt are monodrome functions of temperature, and the relation between v(T) and d(T) is a linear function, i.e., v = v (0) + K center dot d(T). This relation indirectly verifies the calculation model of the structural information of metal melt, which is of great significance for studying the relation between melt microstructure and macro-physical properties.
