Abstract
The superconducting resistive critical field Hr of the bcc region of the Ti–Nb–V ternary system has been studied. Measurements at 4.2°K on cold‐rolled alloys at 10 at.% composition intervals determined that Hr varied smoothly with composition. A maximum in Hr occurred at a valence electron to atom ratio n of 4.4 for pseudobinaries of the system. The ratio of critical field to transition temperature was found to be a function of n alone in qualitative accord with the theory for type II superconductors. A criterion for predicting the behavior of similar systems is presented.Keywords
