摘要

本文介绍了Fe–N和Fe–Ga系统在大气压（0.1 MPa）和高压（3、5和7 GPa）下的熔解图计算结果。热力学计算是在现象学热力学模型中进行的。如图所示，压力的增加导致Fe–N系统中高温b.c.c.Fe改性的不稳定，以及Fe4N与液相平衡的稳定。在Fe–Ga系统中，金属间化合物Fe3Ga、Fe6Ga5、Fe3Ga4和FeGa3在7 GPa的压力下保持其稳定性。Fe4N与液相在高压下的平衡稳定表明，在Fe–Ga–N系统熔体的氮化镓结晶中，Fe4N可能是竞争相。

Thermodynamic Calculation of Fe–N and Fe–Ga Melting Diagrams at Pressures from 0.1 MPa to 7 GPa

This paper presents results of melting-diagrams’ calculations for the Fe–N and Fe–Ga systems at atmospheric pressure (0.1 MPa) and at high pressures (3, 5, and 7 GPa). Thermodynamic calculations are performed within the models of phenomenological thermodynamics. As shown, the increase of pressure results in destabilization of high-temperature b.c.c.-Fe modification in Fe–N system and stabilization of Fe4N equilibrium with the liquid phase. In Fe–Ga system, the intermetallic compounds Fe3Ga, Fe6Ga5, Fe3Ga4, and FeGa3 retain their stability up to pressure of 7 GPa. The stabilization of Fe4N equilibrium with the liquid phase at high pressures indicates that the Fe4N can be a competing phase in the gallium-nitride crystallization from the Fe–Ga–N system melt.

期刊介绍： The review journal Uspehi Fiziki Metallov (abbreviated key-title: Usp. Fiz. Met.) was founded in 2000. In 2018, the journal officially obtained parallel title Progress in Physics of Metals (abbreviated title — Prog. Phys. Met.). The journal publishes articles (that has not been published nowhere earlier and are not being considered for publication elsewhere) comprising reviews of experimental and theoretical results in physics and technology of metals, alloys, compounds, and materials that possess metallic properties; reviews on monographs, information about conferences, seminars; data on the history of metal physics; advertising of new technologies, materials and devices. Scope of the Journal: Electronic Structure, Electrical, Magnetic and Optical Properties; Interactions of Radiation and Particles with Solids and Liquids; Structure and Properties of Amorphous Solids and Liquids; Defects and Dynamics of Crystal Structure; Mechanical, Thermal and Kinetic Properties; Phase Equilibria and Transformations; Interphase Boundaries, Metal Surfaces and Films; Structure and Properties of Nanoscale and Mesoscopic Materials; Treatment of Metallic Materials and Its Effects on Microstructure and Properties.
