摘要

In the current study, jump stress creep and stress relaxation experiments were performed to Zr₆₅Cu₁₈Ni₇Al₁₀ metallic glass below the transition temperatures Tg. The viscoplasticity effect and transition between the Newtonian and non-Newtonian flow are investigated. The activation energy of creep is obtained from two theoretical methods. It is found that the activation volume of creep is more than that of stress relaxation, which is mainly caused by different organizational behaviors.
