Thermodynamics of High Temperature Materials
Abstract
Heat capacity, electrical resistivity, total hemispherical emittance of carbon composite (supplied by AFML), and palladium, radiance temperature at melting point of palladium, heat of fusion of niobium measured. Electrical system of pulse interferometer for thermal expansion and system for thermal diffusivity completed. Enthalpy measurements to 1200 K on Silicon nitride made. Analysis of silicon carbide completed and enthalpy measurements made to 770 K. Computer codes for direct sum technique to assess effect of vibrational thermodynamic functions completed and tested. Vibrational assessments for two silicon fluoride bromide species completed. Direct sum programs for thermodynamic functions for several Hund's coupling cases completed.
