Abstract

The kinetics of structural relaxation in fragile glass former, Pd ₄₆Cu_35.5P_18.5 BMG, and strong glass former, Zr₅₀Cu₄₀Al₁₀ BMG, was investigated by volume relaxation. The former exhibited a relaxation phenomenon that is well understood by the local topological instability model, while the latter showed monotonous relaxation behavior over a wide range down to T_g-60 K. The discrepancy may be closely related to the difference in the fragility of both glasses.
