The influence of quenching condition on the aging and the rejuvenation effect was investigated by classical molecular-dynamics simulations on CuZr metallic glasses under oscillatory shear. Atomic dynamics underlying this procedure is focused. We found a separation of fast and slow atoms in the non-equilibrium state, with an exponential tail in the displacement distribution function contributed by the fast atoms, similar to that in the glass-forming liquids. However, we do not observe any localized relaxation process, e.g., the cage relative motion, which is prominent in the supercooled liquids. Structural relaxation in the fluidized glasses exhibits a simple exponential decay, in contrast to the stretched exponential law in liquids. This dynamic significance is ascribed to the subextensive feature of the atomic displacement in the sheared amorphous solids.
