NUCLEATION EFFECTS DURING CRYSTALLIZATION IN DISORDERED METASTABLE METALLIC SYSTEMS

Dušan Müller – Peter Švec

   The study of some new methods for investigation of amorphous and nanocrystalline aluminium based alloys will be presented. Nanocrystalline alloys obtained by crystallization from amorphous rapidly quenched Al-Rare Earth-Transition Metal systems were investigated. Noise analyses technique was used for investigation of these systems. The main visible activity in this field is low frequency noise, also called 1/f noise. Changes in noise manifestation during measurements, which can contribute to characterization of materials, were observed.

Keywords: crystallization, 1/f noise, nucleation rate
