This work devotes to consider an underlying mechanism of the ultrasound-induced instability phenomenon observed for some metallic glasses. Mechanical spectroscopy analysis strongly suggests that the instability is caused by that atomic motions associated with the relaxation are resonant with the periodic ultrasonic-strain field. It is reasonable to consider that such atomic motions at temperatures lower than the kinetic freezing temperature Tg originates from relatively weakly bonded regions in an inhomogeneous microstructure of glass.
