摘要：

The temperature and time dependences of kinematic viscosity in Al86Ni8(La/Ce)(6), Al86Ni6CO2Gd4(Y/Tb)(2) melts over the range of liquidus up to 1300 degrees C have been investigated. An irreversible non-monotonic change of the melts viscosity above the temperature of melting brought about by the destruction of their microheterogeneous state inherited from the multi-phase solid sample has been found out. It is shown that for the melts transition into the quasi-equilibrium state long isothermal holding is necessary. The relaxation time decreases with the increase of the melt temperature.
