ABSTRACT:

Temperature and time dependences for viscosity of the Al87Ni8Y5, Al86Ni8La6, Al86Ni8Ce6 liquid alloys and the Al-Ni and Al-Y molten binary systems with the aluminum content as high as 90 at.% were studied. Non-monotonic relaxation processes in the Al-Y, Al-Ni-(La/Y/Ce) alloys after the crystal-liquid transfer, determined by the destruction of non-equilibrium condition were found. It was revealed that the non-equilibrium condition is inherited from the original heterogenic solid alloy. The mechanism of such processes was suggested.
