TERNARY PHASE EQUILIBRIA IN TRANSITION METAL-BORON-CARBON-SILICON SYSTEMS. PART 4. THERMOCHEMICAL CALCULATIONS. VOLUME 2. THERMODYNAMIC INTERPRETATION OF TERNARY PHASE DIAGRAMS

Abstract

The equilibrium conditions for two-phase and three-phase equilibria in ternary systems are derived from the minimum condition for the free energy, and special solutions are discussed on model examples. The predictive capabilities of the thermodynamic approach are demonstrated on a number of refractory carbide systems, and methods for the determination of phase stabilities from experimental phase equilibrium data are outlined. The thermodynamic discussions are supplemented by a general review of recent phase diagram work on refractory transition metal-B element systems.
