Image of FIG. 1.
FIG. 1.

Normalized shear modulus change for bulk glassy in the annealed states. The inset shows the low-temperature data on an enlarged scale. Cycles 1 to 4 are highlighted by arrows.

Image of FIG. 2.
FIG. 2.

Relaxation of preannealed sample 1 upon increasing temperatures. The inset gives the minimal normalized shear modulus change achieved at different testing temperatures. Open symbols, closed triangles, and closed circles correspond to the samples 1, 2, and 3, respectively.

Image of FIG. 3.
FIG. 3.

Temperature dependencies of the metastable equilibrium shear modulus together with the metastable equilibrium defect concentration. The solid lines give the least-square-fits. The Kauzmann pseudocritical temperature together with the calorimetric glass transition temperature are indicated.

Image of FIG. 4.
FIG. 4.

Schematic drawing of the Gibbs free energy of glass at a constant temperature as dependent on the interstitialcy defect concentration. The as-prepared and strongly annealed states of glass and the corresponding relaxation routes (A and B) towards the metastable equilibrium are indicated.
