TERNARY PHASE EQUILIBRIA IN TRANSITION METAL-BORON-CARBON-SILICON SYSTEMS. PART II. TERNARY SYSTEMS. VOLUME X. THE ZR-SI-C, HF-SI-C, ZR-SI-B, AND HF-SI-B SYSTEMS

Abstract

Phase equilibria and mutual solubilities in the Zr-Si-C, Hf-Si-C, and Hf-Si-B ternary systems have been determined at 1300 C. The general melting behavior and high temperature mutual solubilities in the Zr-Si-C, Hf-Si-C, Zr- Si-B, and Hf-Si-B systems have been studied; minimum melting temperatures along various pseudo-binary sections are given. All four systems are characterized by the formation of a ternary D8(8)-Nowotny phase. Most melting temperatures in the ternary systems are governed by the lower melting binary silicide compounds. Guidelines for feasible high temperature applications are given.
