英文摘要	In the current work, we demonstrated that the rejuvenation of metallic glasses can be achieved through training the beta relaxation process. With the increase in the training frequency, a transition from structural relaxation to rejuvenation can be observed. This rejuvenation treatment is unexpected due to it occurs at a relatively small cyclic strain of 0.2%. Rejuvenation is beneficial to increase the relaxation enthalpy and promotes the decoupling of the beta relaxation process and arelaxation process. A cluster of beta relaxation time curves are formulated to describe any energetic state between ultrastable and ultimately rejuvenated metallic glasses. In addition, rejuvenation expands the distribution of beta relaxation process, anelastic and viscoplastic components during the deformation process.
