Fast relaxation in metallic glasses studied by measurements of the internal friction at high frequencies
G. V. Afonin, J. C. Qiao, A. S. Makarov +2
We performed high-frequency (0.4 to 1.7 MHz) measurements of the internal friction (IF) on 14 bulk metallic glasses (MGs). It is found that 12 of these MGs display relaxation IF pe…
High entropy metallic glasses, what does it mean?
G. V. Afonin, J. C. Qiao, A. S. Makarov +4
We performed calorimetric measurements on 30 bulk metallic glasses differing with their mixing entropies DSmix. On this basis, the excess entropies DS and excess enthalpies DH of g…
Effect of the entropy on the shear viscosity of metallic glasses near the glass transition
A. S. Makarov, J. B. Cui, J. C. Qiao +3
We measured the shear viscosity of 14 metallic glasses differing with their mixing entropy . It is found that the viscosity at the glass transition temperature sign…
Dimensionless parameter of structural ordering and excess entropy of metallic and tellurite glasses
A. S. Makarov, G. V. Afonin, R. A. Konchakov +4
Using a notion on the excess entropy of glass with respect to the counterpart crystal, we introduce a simple dimensionless order parameter , which changes from …
Critical behavior of the fluctuation heat capacity near the glass transition of metallic glasses
R. A. Konchakov, A. S. Makarov, G. V. Afonin +4
The high-frequency shear modulus of five Zr-, Pd-, Cu-based conventional and two high-entropy bulk metallic glasses was measured in a wide temperature range up to the beginning of…
Defect-induced ordering and disordering in metallic glasses
A. S. Makarov, G. V. Afonin, R. A. Konchakov +4
On the basis of shear modulus measurements on a Pt-based glass, we calculated temperature dependence of the defect concentration c using the Interstitialcy theory. This temperature…
