Two phenomenological theories were investigated for describing the reversible structural relaxation in metallic glasses: the activation-energy spectrum model of two-level systems and the diffusion model based on the free volume theory, where the driving force is thought to be compositional ordering of different types of atoms. Two kinetic curves were measured and compared with those calculated from the models. For comparison the whole annealing procedure performed in the experiment was taken into account by using a new evaluation technique. In the temperature range investigated (160-270 degrees C) for Ni 60Fe20P20 the diffusion picture seems to describe the data better.
