We determine the kinetic parameters of crystallization of amorphous metallic alloys based on aluminum doped with rare-earth metals (REM) by the method of differential scanning calorimetry. It is shown that the amorphous metallic alloys based on aluminum crystallize in three stages. By using the Kissinger, Avrami, and Ozawa models, we compute the energies of activation for the first stage of crystallization on the basis of the results of differential scanning calorimetry. It is shown that the Al–REM–Ni alloys are nanocrystallized by a kinetically controlled mechanism. The substitution of Gd for Y leads to a decrease in the temperature of nanocrystallization by 20–40°K. At the same time, the substitution of Dy for Y leads to an increase both in the temperature of nucleation and in the temperature of growth of nanocrystals. As a result of the addition of Fe to the composition of the alloy, the range of nanocrystallization shifts by about 100°K. According to the Matusite model, for constant temperatures of phase transitions, it is shown that the growth of nanocrystals in amorphous metallic alloys of the Al–REM–Ni system is realized in the 1D direction and linearly (interface control). In amorphous alloys, Dy substantially increases the temperatures of phase transitions and the number of atoms in clusters and decreases the microhardness.
