TERNARY PHASE EQUILIBRIA IN TRANSITION METAL-BORON-CARBON-SILICON SYSTEMS. PART II. TERNARY SYSTEMS. VOLUME XIII. PHASE DIAGRAMS OF THE SYSTEMS TI-B-C, ZR-B-C, AND HF-B-C

Abstract

The ternary alloy systems Ti-B-C, Zr-B-C, and Hf-B-C have been investigated by means of X-ray, metallographic, melting point, and differential- thermoanalytical techniques. The experimental alloy material comprised of hot- pressed and sintered, arc- and electron-beam molten, as well as high temperature equilibrated and quenched, specimens; each phase of the experimental work was supported by chemical analysis. The results of this investigation are discussed and possible fields of application outlined.
