摘要
The anelastic relaxation behavior of amorphous Al86.8Ni3.7Y9.5 was characterized in prolonged, quasistatic measurements, up to 1.1 x 10(8) s. The size-density distribution of potential shear transformation zones was determined from the data. We derive an expression for the distribution, based on a free-volume criterion for an atomic cluster being a potential shear transformation zone. The model is shown to be consistent with experiment.
