The fluidity of liquid metals, like that of simple nonmetallic liquids, is a linear function of the ratio of unoccupied volume to intrinsic volume over long ranges as expressed by the equation φ = B[(V/V0) - 1]. Values of V0obtained by extrapolating to φ = 0 agree well with molal...
Two approaches to the wave-number dependent viscosity n(q) of liquid metal Rb are compared. The first is based on the two-component theory of a liquid metal, and expresses n(q) in terms of the ionic static structure factor S(q) plus elastic scattering data. The second describes the ion...
Viscosity is an important property which could determine the flow liquid metal characteristics and reflect the liquidus structure. Therefore, the existence of an accurate model is necessary to calibrate the experimental measurement value of viscosity. At present, many models have been proposed to ...

On the theoretical side, such data would provide further information towards the understanding of the liquid state, while, in the field of applied metallurgy, the viscous nature of liquids is tied closely with the flow behaviour of metals in filling moulds. The paucity of data in these fields ...
It is shown that a simple empirical relationship exists between the activation energy of viscosity for liquid metals and their melting points. This relationship coupled with Da Andrade's expression for the viscosity of the liquid metal at the melting point ( T m.p.): ν m.p.(in poises)=5...
Knowledge of the viscosity and its temperature dependence is essential to improve metallurgical processes as well as to validate theoretical and empirical models of liquid metals. However, data for metals with melting points above2504Kcould not be determined yet due to contamination and containment prob...
