Phase transformations of Fe3N-Fe4N iron nitrides at pressures up to 30 GPa studied by in situ X-ray diffractometry / K. D. Litasov [et al.]> // JETP Letters. - 2014. - Vol. 98, Is. 12. - P. 805-808, DOI 10.1134/S0021364013250140. - Cited References: 23. - This work was supported by the Ministry of Education and Science of the Russian Federation (project nos. 14.B37.21.1261 and 14.B25.31.0032) and, in part, by the Siberian Branch, Russian Academy of Sciences (integration project no. 97 for 2012-2014). The experiments were performed in cooperation between the Sobolev Institute of Geology and Mineralogy, Siberian Branch, Russian Academy of Sciences, and Tohoku University (Global Center of Excellence program "Advanced Science and Technology Center for the Dynamic Earth").

The parameters V-0 = 81.48(2) angstrom(3), K-T = 162(3) GPa, K-T = 4.0 = 1.66(2), gamma(0) = 555 K, and q = 1 have been determined for epsilon-Fe3N0.8 by the approximation of the P V T data with the Vinet equation of state and the thermal parameters within the formalism. No anomalous change in the volume of the cell owing to possible magnetic transitions has been revealed. The instability of Fe4N at high pressures and Fe3N in the presence of a deficit of nitrogen in the system has been established. The stable phase in the temperature range of 300-673 K and the pressure range of 20-30 GPa is epsilon-Fe3N rather than epsilon-Fe3N0.8.
