Abstract
The aim was to investigate the characteristics of the short-range structure and the nanocrystallization kinetics of amorphous alloys in the heat treatment of amorphous alloys. On the basis of X-ray research it is established that at the first stage of primary crystallization (418–465 K) there is a simultaneous nucleation and three-dimensional growth of Al-nanocrystals. Within temperature range 465–580 K the probability that new Al - nuclears are created significantly decreases due to that amorphous phase is enriched with Ni and Dy atoms and the diffusion controlled growth of Al-nanocrystals is the main contribution into kinetics of transformation.
