Relationship between the shear modulus and volume relaxation in high-entropy metallic glasses: experiment and physical origin
R. S. Khmyrov, A. S. Makarov, J. C. Qiao +2
We performed parallel measurements of the high-frequency shear modulus and relative volume for high-entropy TiZrHfBeCu and TiZr…
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…
Relation of the thermodynamic parameter of disordering with the width of structure factor and defect concentration in a metallic glass
G. V. Afonin, A. S. Makarov, R. A. Konchakov +4
In this work, we show that above the glass transition there exists a strong unique interrelationship between the thermodynamic parameter of disorder of a metallic glass derived usi…
