Using the results of self-consistent relativistic APW band structure calculations, and the measured phonon spectra, we have calculated the electron-phonon interaction and lamda for the compounds PdD, NbC, TaC, HfC and V3Si, based on an extension of the theoretical formulation of Gaspari and Gyorffy. We discuss and contrast the nature of superconductivity in these different materials, and give an extended explanation of the relationship between superconductivity, phonon anomalies and chemical bonding as mirrored in the Fermi surface of the refractory carbides.
