On the structural stability of metallic glasses
Tóm tắt
We discuss the various possibilities advanced to account for the structural stability of metallic glasses. Using a formalism based on the pseudopotential theory and the Gibbs-Bogoliubov inequality we calculate the free energies and free energies of formation for the glassy phase of MgCa at various concentrations and compare these results with those for the corresponding solid and liquid phases of the same system. Subsequently, we attempt to explain the stability of the metallic glasses by noting a matching between the positions of the first peakq
m in the relevant structure factor and the maximumq
s in the relevant screened pseudopotential.
