Metallic glasses (MGs), with their unique structure and excellent properties, have become one of the most attractive topics in the field of condensed physics and materials science. As a metastable material, MGs trend to undergo the transition towards a more stable low-energy state under applied stress or high-temperature, known as aging or structural relaxation, accompanied with the decrease in deformability at room temperature. Rejuvenation in MGs, a converse process of ageing/relaxation, which brings materials to the younger 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 for exploring the atomic structure, glass transition and deformation mechanisms of MGs. Here, we will introduce the recent progress in the study of rejuvenation, including the methods of rejuvenation of MGs, the effect of rejuvenation behavior on microstructure and mechanical properties.
