A detailed study of the effect of annealing on the internal friction of metallic glass Fe/sub 32/Ni/sub 36/Cr/sub 14/P/sub 12/B/sub -/ measured by the inverted torsion pendulum method is presented. It was found that the glass reaches, after an extended period of annealing, an internal pseudo-equilibrium state as far as the internal friction is concerned, which is a function of the annealing temperature. A change in the annealing temperature results in a reversible change from one such state to another. The authors present a phenomenological model which explains the dependence of the pseudo-equilibrium state upon both the annealing temperature and measuring temperature and the kinetics of the transition from one to another, and discuss its relation to atomic level structural fluctuations.
