Abstract
A previous calculation of the superconducting transition temperature Tc in a strong-coupling localized formulation that was performed on V, Nb, and Ta is extended to bcc transition-metal alloys in the 3d, 4d, 5d rows of the periodic table, giving a nice quantitative agreement with experiment. The pressure dependence of Tc for some elements and for Zr-Nb-Mo alloys is calculated and compared with experiment.
