Fig. 4: Relaxation kinetics.
Evolution of (Top) the activation energy \({E}_{a}\) and (Bottom) the fraction of strain recovery (\({1-\varepsilon }_{{vp}}/{\varepsilon }_{1}\)) with tw for a TiZrHfCuNiBe MG, b (Fe11Zr1)91.2B8.8 MG, and c PVC polymer. The experimental condition for strain recovery tests: Ti-MG (Ta = 593 K, \({\varepsilon }_{1}\) = 0.5%), Fe-MG (Ta = 597 K, \({\varepsilon }_{1}\) = 0.4%), and PVC (Ta = 318 K, \({\varepsilon }_{1}\) = 0.5%). (Calculation details for the activation energy and fraction of strain recovery are presented in sections 4 and 5 of Supplementary information). Source data are provided as a Source Data file.
