英文摘要In contrast to their conventional crystalline counterparts, amorphous solids exhibit diverse dynamic relaxation mechanisms under external stimuli. The challenge to understanding their behavior lies in unifying microscopic dynamics, relaxation, and macroscopic deformation. This study establishes a potential link by quantifying the characteristic time of the anelastic-to-plastic transition through dynamic mechanical relaxation and stress relaxation tests across a wide temperature range in both the supercooled liquid and the glassy state. It is found that the stress relaxation time in the glassy solids follows an Arrhenius relationship, aligning with the main alpha relaxation time, and unveils a finding: alpha relaxation continues to govern deformation even below the glass transition, challenging previous assumptions of the role of secondary beta relaxation. A hierarchically constrained atomic dynamics model rationalizes the temperature dependence of alpha relaxation and the transition from beta to alpha relaxation, also providing evidence that the stretched exponent in the Kohlrausch-Williams-Watts equation can serve as an order parameter. This work highlights the role of alpha relaxation in the glassy state and contributes to elucidating the potential correlation between relaxation and deformation in amorphous materials.
