Abstract : Formulas are given both for the volume dependence of the transition temperature Tc of transition metals and for the Tc of well-ordered A15 compounds. Both formulas yield results in reasonable agreement with experiment. Measurements are proposed to facilitate further comparison with experiment. Hopfield's explanation of the high Tc of some A15 compounds is supported. Finally, it is shown why phonon-softening effects are unlikely to yield high transition temperatures for transition metals or transition-metal compounds. (Author)
