Relationship of structural disorder and stability of supercooled liquid state with glass-forming ability of metallic glasses

J. B. Cui, R. A. Konchakov, G. V. Afonin +5

We performed calorimetric studies of 26 metallic glasses and calculated the excess entropy and excess enthalpy with respect to their counterpart crystals. On this basis, we introdu…

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…
