TERNARY PHASE EQUILIBRIA IN TRANSITION METAL-BORON-CARBON-SILICON SYSTEMS. PART II. TERNARY SYSTEMS. VOLUME 5. TI-HF-B SYSTEM

Abstract

A complete phase diagram for the ternary alloy system titanium- hafnium-boron from 1000 C through the melting ranges of the diborides was established on the basis of X-ray, melting point and metallographic studies. The outstanding features of the system are that both the metal diborides and monoborides form continuous solid solutions with respect to metal exchange. From the distribution of the tie-lines in the metal monoboride two-phase field, the Gibbs free energy difference between the titanium monoboride and hafnium monoboride was derived.
