Modeling of glass transition process and elastic properties of Zr-Nb amorphous alloys

The glass transition of supercooled Zr - Nb melt was studied by molecular dynamics modeling. Glass transition temperature was determined using by different criteria such as change of the heat capacity, diffusion coefficient and viscosity, the obtained data are in good agreement with each other. It is shown, that elastic modulus rise with the decrease of the free volume in structure, that agrees with the supposed model of the amorphous alloys' deformation.

Automated summary

The glass transition of supercooled Zr-Nb melt was studied by molecular dynamics modeling, with glass transition temperature determined using various criteria such as change of heat capacity, diffusion coefficient, and viscosity. It was found that the elastic modulus increases with the decrease of free volume in the structure, in accordance with the supposed model of deformation in amorphous alloys.
