| Abstract | Glasses with rejuvenated structures usually exhibit improved room-temperature plasticity, which facilitates their applications. However, glass rejuvenation requires external energy injection to "shake up" the frozen-in disordered structure. In this work, we give the answer to how much the required energy is. According to the constitutive model of amorphous plasticity, we find that the applied stress higher than the steady-state flow value can effectively induce the structural disordering in terms of the generation of free volume. Therefore, the effective energy density (EED) of structural rejuvenation is defined as the integral of this effective stress on the corresponding strain. By tailoring the applied strain, strain rate, temperature and initial free volume, different degrees of structural rejuvenation are achieved, which show a generally linear correlation with the defined EED. This work deepens the understanding of glass rejuvenation from an energy perspective. |
