Abstract: Precision in situ measurements of the shear modulus of bulk metallic glass based on Zr have been performed. The contribution to the shear modulus due to the structural relaxation has been separated. Based on the interstitial theory, the relaxation model explaining the obtained experimental results has been constructed.
