Viscosity and relaxation processes of the liquid become amorphous Al-Ni-REM alloys

The temperature and time dependencies of viscosity of the liquid alloys, Al87Ni8Y5, Al86Ni8La6, Al86Ni8Ce6, and the binary Al-Ni and Al-Y melts with Al concentration over 90 at.% have been studied. Non-monotonic relaxation processes caused by destruction of nonequilibrium state inherited from the basic-heterogeneous alloy have been found to take place in Al-Y, Al-Ni-REM melts after the phase solid-liquid transition. The mechanism of nonmonotonic relaxation in non-equilibrium melts has been suggested.
