Equation of State and Thermal Properties of Bulk Metallic Glass under High Compressions

Abstract

Studies on the equation of state (EOS) for solids are highly valuable in the field of condensed matter physics and geophysics. The analyses of the equation of state under high compressions for solids are already performed. In the proposed study, we have considered the four different approaches (finite strain and interionic potential) to study P-V-T relationship for amorphous glasses. The theoretically obtained results are compared with available experimental data to compare and verify the best suitable equation of state for amorphous solids like glass, which can be used in the future to find the thermodynamic parameters of bulk metallic glass, which is also an amorphous solid in total. The results obtained from Shanker EOS and higher-order Shanker EOS are found to be more consistent with the experimental results. We calculate the Grüneisen parameter and thermal conductivity for the bulk metallic glasses (window and water white glasses) under high compressions.
