Role of rare-earth metals (R) in the appearance of relaxation processes in AL-Ni-R metal melts.

The temperature and time dependences of the viscosity of liquid ternary alloys AlNiY, AlNiLa, AlNiCe, AlNiCo, AlNiCoand binary melts Al(Y/Ni/Co)have been studied after different temperature-time treatment of the melt. It is shown that long-time relaxations in the Al-TM-R melts occur only after the phase transition 'crystal-liquid' due to the melt transition from the non-equilibrium to equilibrium state. The non-equilibrium state of the melt appears due to inheriting non-equilibrium atomic groups during melting; the atomic groups have ordering characteristic of chemical compounds of the AlRtype present in solid-state alloys.
