Relaxation dynamics,essential for the structural evolution of non-equilibrium systems like glassy materials,remain enigmatic.Here,we explore relaxation dynamics and viscoelastic properties in three types of metallic glasses with distinct β relaxation behavior.In systems with significant β relaxation,stress relaxation and creep experiments reveal a transition from two-step to one-step relaxation with rising temperature.However,such a phenomenon is absent in systems with weaker β relaxation.We model the two-step relaxation process using a double Kohlrausch-Williams-Watts equation,and the obtained relaxation times elegantly adhere to the Arrhenius relationship.By combining fitted activation energies with theoretical analysis,we conclusively attribute these relaxation processes to β relaxation and α relaxation,respectively.Finally,we analyze the relaxation time spectra of two processes and establish a comprehensive picture linking dynamic relaxation with viscoelasticity.Our study provides new strategies for probing the complex relaxation behaviors of glasses from the perspective of viscoelasticity.
