Abstract: We have studied the temperature and the temporal dependences of the viscosity of quasi crystalforming AlAlCuCuFeFe melts within the range of ii-phase (Al62Cu25.5Fe12.5)(Al62Cu25.5Fe12.5) stoichiometry with a change in the concentration of copper from 15.515.5 to 35.535.5 at %% and in that of iron from 2.52.5 to 2222 at %% as well as within the concentration range in which the ii-phase is the first to arise from the Al59.5+xCu35.5xFe5Al59.5+xCu35.5xFe5 melt (x=0(x=015)15). We show for the studied alloys that prolonged (22 h or longer) relaxation processes take place directly after melting in the conditions of the viscosimetric experiment and that they should be taken into account when the temperature dependences of the viscosity are measured. In the equilibrium thermodynamic conditions, the viscosity polytherms coincide for the heating and the cooling regimes; they are monotonous and are well described by the exponential dependence. The activation energy of the viscous flow, depending on the composition, varies from 1818 to 3636 kJ/mol.
