The correlation of quasistatic and dynamic relaxations was discussed in a typical strong Zr(55)Al(10)Ni(5)Cu(30) metallic glass from room temperature to T(g). The quasistatic relaxation behavior, investigated by high temperature compressive testing at a constant strain rate, was compared with dynamic tensile relaxation behavior. Acorrelation equation of the dynamic frequency and quasistatic strain rate was successfully deduced, and then its validity was experimentally confirmed in a fragile metallic glass. Using this correlation, the Cox-Merz rule, derived for correlating the steady-state and dynamic viscosities of the polymers, is found to be applicable to metallic glasses.
