Metallic glasses (MGs) are one of the most attractive topics in the field of condensed physics and materials science because of their unique structure and excellent properties. As a metastable material, MGs tend to present a transition toward a more stable low-energy state under applied stress or high-temperature, known as aging or structural relaxation, accompanied by a decrease in deformability at room temperature. Rejuvenation of MGs is a converse process of aging/relaxation, which transforms the materials to their previous and higher-energy states. Rejuvenation greatly expands the energy range of MGs, which not only significantly improves the deformation capability of MGs, but also provides a new opportunity to explore the atomic structure, glass transition, and deformation mechanisms of MGs. This article reviews the recent progress in the study of rejuvenation, including the methods of rejuvenation of MGs, the effect of rejuvenation behavior on microstructures, mechanical properties, and functional characteristics. Finally, a brief outlook on the study of the rejuvenation behavior of MGs is presented.
Fig.1 Schematic of aging/relaxation and rejuvenation process in metallic glasses (MGs) drawn according to Ref.[12] (MGs with various glassy states, such as states A, B, C, …, G, could be obtained through different cooling rates. Rejuvenation is the transition process of MGs from lower to higher energy states (from II to I, as indicated by red arrow), while aging/structure relaxation is the transition process from higher to lower energy states (from I to II, as indicated by blue arrow). Tk stands for the finite temperature at which the deepest basins of the landscape are explored. Insets a and b show the typical atomic structures of MGs with high energy and low energy states, respectively)
