Viscosity, electrical conductivity and thermoelectric power of Cu-33.3Bi-33.3Sn, Cu-25Bi-25Sn-25In, Cu-20Bi-20Sn-20In-20Pb and Cu-20Bi-20Sn-20Ga-20Pb liquid alloys of equiatomic concentrations, which are components of model multicomponent high-entropy alloys, have been studied experimentally. Based on the obtained results, the activation energy of the viscous flow and the entropy of mixing were calculated. The negative values of the entropy of mixing suggest a structural ordering in the system.

Key words: high-entropy alloys, entropy, viscosity, electrical conductivity, thermoelectric power
