“…Once the accurate viscosity is predicted, the reliable tracer diffusivity can be evaluated by the Stokes-Einstein or Sutherland-Einstein relation. Several viscosity models in liquid alloys have been proposed in the literature, and each one is only valid in specific systems [57,58]. The comprehensive comparisons between the experimental viscosities and the data predicted from different semi-empirical models indicate that the Kozlov model can be adopted to predict the reasonable viscosity data in alloy melts [14].…”

Multicomponent diffusion in metallic melts is a very important phenomenon during the solidification/casting process of the metallic alloys. However, there exist extremely limited reports on the diffusivity information in multicomponent metallic liquids. In this chapter, a universal and effective phenomenological approach to predict the composition– and temperature–dependent diffusivities in liquid multicomponent systems is systematically proposed. The presently proposed phenomenological method is then adopted to construct the diffusivity/mobility databases of liquid solders, cemented carbides, Co–Cr–Fe–Mn–Ni high entropy alloys and Al–Ce–Ni alloys. Then, the accurate diffusivity/mobility data are further utilized to perform the simulations of the dissolutions of the substrate into the solders, the gradient layer formation of the cemented carbides, the diffusion behavior of liquid Co–Cr–Fe–Mn–Ni high entropy alloys and the rapid solidification of Al–Ce–Ni system. The simulated results indicate that the presently proposed phenomenological method is applicable to investigate the diffusion kinetics in multicomponent metallic melts.
