The amorphous Ti40.7Hf9.5Ni44.8Cu5 melt-span ribbon samples were subjected to low-frequency vibrations (20 Hz) with an amplitude of 1 or 4 μm at room temperature to study the influence of the vibrations on the structural relaxation and the crystallization of amorphous alloy. The results obtained showed that the samples retained the amorphous structure after low-frequency vibrations but the resistivity decreased due to some structural relaxation. It was found that the low-frequency vibrations with an amplitude of 4 μm led to the formation of nanoclusters with ordered atomic position in the amorphous structure, but it hardly affected the crystallization temperatures.
