Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Amorphous Materials

Background:

  • Metallic glasses (MGs) typically show only slow beta-relaxation.
  • Observing fast dynamics in MGs experimentally is challenging.
  • Understanding relaxation dynamics is crucial for MGs' properties.

Purpose of the Study:

  • To report a general and unusual fast dynamic mode in rare earth based MGs.
  • To characterize the fast beta-prime relaxation peak.
  • To investigate the relationship between dynamics, glass transition, and structural heterogeneity.

Main Methods:

  • Experimental observation of relaxation peaks (alpha, beta, and beta-prime).
  • Analysis of activation energy for the fast beta-prime relaxation.
  • Discussion of dynamic coupling and structural heterogeneity.

Main Results:

  • A distinct fast beta-prime relaxation peak was observed in rare earth based MGs.
  • The activation energy of the fast beta-prime relaxation is approximately 12RTg.
  • This fast relaxation is equivalent to localized flow events.

Conclusions:

  • A general fast dynamic mode exists in rare earth based MGs.
  • The fast beta-prime relaxation is linked to localized flow events.
  • The study provides insights into the coupling of dynamic processes and structural heterogeneity in MGs.
