In this work, we have investigated the dynamic shear modulus of the bulk Zr{sub 55}Cu{sub 25}Ni{sub 5}Al{sub 1}Nb{sub 5} metallic glasses over large temperature and frequency ranges. Like in other conventional glass forming systems, a distinct {alpha} relaxation with typical kinetic features is experimentally detected. Therefore, the fragility parameter, m, which is estimated from the activation energy for viscoelastic deformation, indicates that the Zr base bulk amorphous alloy is a relatively strong liquid. On the other hand, during the main mechanical relaxation, the frequency dependence of dynamic shear modulus of the Zr base bulk amorphous alloy follows the biparabolic equation derived from a physical model, which can characterize the atomic mobility and mechanical response of disordered condensed materials.
