| Popis: | Taking into account the influence of temperature, we investigated the thermoelasticity properties of FeSi under high pressure. The obtained relationship of pressure and volume agrees well with the experimental data at high pressures. We found the anisotropy factor and sound velocities are significantly affected by pressure whereas they are insignificantly affected by temperature, especially at high pressures. The different propagating directions almost have no effect on the compressional wave velocities at high pressures and different temperatures. |
