Abstract : The intemal friction and the rigidity modulus of an amorphous Zr67Fe33 alloy have been measured in an inverted torsion pendulum apparatus with a frequency range of 0.3-2 Hz. The rigidity modulus increases irreversibly with the annealing which suggests a two-step structural relaxation. It is clarified that the internal friction due to the structural relaxation and the crystallization depends on the heating rate and the vibrational frequency. It is suggested that the internal friction has a -transient component- which is proportional to the amount of structural change during one period of the vibration.
