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
