Реферат:	rus: На основе свободной энергии Гельмгольца построено уравнение состояния железа с объемно-центрированной кубической решеткой (bcc-Fe) путем одновременной оптимизации ультразвуковых, рентгеновских, дилатометрических и термохимических измерений в температурном интервале от 100 К до температуры плавления и до давления 15 ГПа. Рассчитанные термодинамические функции bcc-Fe хорошо согласуются со справочными данными и экспериментальными измерениями при атмосферном давлении, а также с P-V-T измерениями в области температур до 773 К и давлений до 16 ГПа. Приведена табуляция термодинамических функций bcc-Fe (x, a, S, C P, C V, K T, K S, γ, K', G T,P) до температуры 1811 К и давления до 15 ГПа. Рассчитанные P-V-T соотношения bcc-Fe могут быть использованы для расчета давления при заданных температурах и объемах. eng: Based on Helmholtz's free energy, an equation of state of iron (bcc-Fe) is constructed with simultaneous optimization of ultrasonic, X-ray diffraction, dilatometric, and thermochemical measurements in the temperature range from 100 K to the melting points and pressures up to 15 GPa. Calculated thermodynamic functions of bcc-Fe are in good agreement with the reference data and experimental measurements at room pressure, as well as with P-V-T measurements at temperatures up to 773 K and pressures up to 16 GPa. The calculated thermodynamic properties of bcc-Fe (x, α, S, C P, C V, K T, K S, γ, K', G T,P) are tabulated up to 1811 K and 15 GPa. The calculated P-V-T relations for bcc-Fe can be used to calculate pressures at given temperatures and volumes.
