TERNARY PHASE EQUILIBRIA IN TRANSITION METAL-BORON-CARBON-SILICON SYSTEMS. PART 2. TERNARY SYSTEMS. VOLUME 6. ZR-HF-B SYSTEMS

Abstract

The ternary system zirconium-hafnium-boron has been established for temperatures above 750 C with the air of melting point, X-ray, and metallographic investigations of chemically analyzed alloys. A brief thermochemical evaluation of the system was made at 1400 C, and the Gibbs free energies of formation for both the hafnium monoboride and hypothetical zirconium monoboride were calculated. The zirconium-hafnium system was reviewed using differential-thermal analytical techniques, and the proposed binary diagram is given.
