Abstract

The solubility limits for hydrogen and deuterium in niobium were determined resistometrically between 175 and 280°K before and after purification of the niobium by ultra-high vacuum treatment. No isotope effect was observed; neither was an interstitial impurity effect detected in the low concentration range studied. The solubility limits for hydrogen in vanadium were measured at temperatures between 230 and 325°K before and after additions of oxygen greater than 1000 at. ppm. Large concentrations of solute oxygen increase the apparent solubility limit for hydrogen in vanadium.
