RESEARCH STUDY TO DETERMINE THE PHASE EQUILIBRIUM RELATIONS OF SELECTED METAL CARBIDES AT HIGH TEMPERATURES,
Abstract
The work summarized in the report is the result of investigations of phase equilibria in the binary systems, tantalum-carbon, hafnium-carbon, and boron-carbon. A completed phase diagram which encompasses experimental results and considerations heretofore unreported in the literature, is presented for the hafnium-carbon system. A phase diagram for the tantalum-carbon system is included. Preliminary studies on the hafnium carbidetantalum carbide quasi-binary were limited to temperatures of 3700 C at which no liquid formation was evident. Results for the boron-carbon system depicting maximum boron solubility in the graphite lattice at and near the eutectic temperature of approximately 2390 C, are also included. (Author)
